I'm experiencing significant delays while using the menu bar on Cognite Notebooks. Specifically, when I try to reopen menus like "File," "Edit," and "View," they take an unusually long time to respond. Additionally, I have a folder named "Notebooks" with several subfolders, and it takes a long time for all the subfolders to display when I try to access them.Has anyone else encountered similar issues? Is there any way to solve these problems?Thanks!

Display events in Cognite Charts which does not have End time.Presently Events does not have End time will not display in Cognite Charts if user try to customize Timeseries for specific duration.Not showing the failures linked to the asset in Charts CDF view, not consistent with the linked failures in Data Explorer. Login to CDF UI Navigate to Data Explorer screen. Click on the Charts tab in menu bar Click on New Chart button. Search Time series name for e.g: FQI02005_M.TOTALIZERA.PV Click on the Time series button below the search field Select the check box of the time series FQI02005_M.TOTALIZERA.PV Click on the Events button on right side of the penal Click on Add Filter button Select the Asset ‘02-V-0203’ from Asset filter. Check Events under the Types filter. Expected Results: User should be able to see & select Events like ‘Failure’, Workorder', ‘MTBE’ etc events for Asset id 02-V-0203Actual Results: Alarm & Failure events not listed under types filter

Doing the ‘hands-on’ for Data Engineer Basics - “Learn to Use the Cognite Python SDK “ Course."I am down to adding events to CDF from  events.csv.I noted that the dataframe df has some entries :NaN” wherever the csv has a blank.Then,However, creating events in CDF fails:the error is: Next, I replace all the csv blank entries with text “blank”, and read into a dataframe. Now the latter does not have any “NaN” values. This throws the same exception when creating events in CDF.If someone can kindly assist, I would be very grateful.Thank you,Doug   

Hi All.I want to deploy multiple PI Extractors on a VM with different configurations and the possibility to start and stop them separately. How can I achieve that? Or do I need to have multiple VMs? Thanks a lot in advance!

How can you with the opc-ua extractor read from the server only some specific tags with some parameter in the YML configuration file?So far with this extractor all tags are sent to CDF.

On behalf of Celanese, I’d like to understand if adding more than one Security Category to a single file or timeseries is supported by the CDF platform and APIs. Also, can it be confirmed that if a certain file is under two categories, only users that are capable of seeing both categories will be able to see it? Thanks!

Is there a way to query metadata of TimeSeries from a particular dataset in CDF Transformations?Something like this, but this query isn’t workingselect  cast(`externalId` as STRING) as externalId,  cast(`dataSetId` as STRING) as eidfrom  `_cdf`.`timeseries`where dataSetId == <data_set_id>;

HiFor a use case I am working on I need to retrieve information about the raw tables in our environment. What I need to do is that i need to retrieve the name of each of the  columns and the datatypes of the columns for every single raw table we have in our environment. I have looked through the python SDK docs, but have not been able to find out how to do this. I noticed that it is possible to do a preview of a transformation through the SDK and get a schema out this way, however this feels a bit too “hacky” and is also very time consuming and inefficient. Does anyone have any idea of how I can get what I need?ThanksSebastian

Here are some issues we are facing with TimeSeriesUploadQueue after migrating to lastest version :Unable to upload rows, though it says it has been uploaded in latest versionIt says uploader uploaded x datapoints even though it doesnt (checked in ui and through api) , and uploaded rows is None even though there are datapoints to upload. Same code works fine in version 6.This is our post upload function: Wrong date range is uploaded in version 7.  (happens on a random basis)The target timeseries didnt exist before we run the extractor. The date range we were trying to upload in the first batch is October 25, 2022 11:38:38.553 PM - December 27, 2022 11:03:47.055 AM and in the second batch is December 27, 2022 7:03:47.055 PM to  January 1, 2023 11:03:47.055 AM( all GMT times)Both batch's upload failed according to sdk (error during callback, rows is NoneType), but somehow 50 datapoints in a completely different date range is written as observed through cognite ui and through sdkWe also fa

(Please forgive the erroneous posting of this under Academy Discussions)Doing the ‘hands-on’ for Data Engineer Basics - “Learn to Use the Cognite Python SDK “ Course."I have done the following:Make a dataframe from reading from a csv file: One of the columns in the csv file is ‘region’. The 5 different values in the region column are  When the above code is run, the  following appears on the screen: Q1. Does this mean pandas has interpreted the region “None” as “nan”? If so that would explain why the following code throws “ValueError: Out of range float values are not JSON compliant. Make sure your data does not contain NaN(s) or +/- Inf!”  I would value your guidance as I have not worked with pandas() much at all.Thank you,Doug  pandas  

Hi,We are using graphql query to get data points in CDF function. As I understand we could retrieve 1,00000 data points at a time if we provide the limit. Here is the sample query:query MyQuery {  listProductionData(    filter: {externalId: {in: ["wellbore1"]}}  ) {    items {      space      data {        Oil {          1_day {            dataPoints(end: 2240591400000, limit: 100000, start: 1672338600000) {              value              timestamp            }          }        }      }    }  }}I tried above query and I can get all the daily datapoints present in the range from  2023-01-01 to 2040-12-31.  But when I tried below query : query MyQuery {  listProductionData(    filter: {externalId: {in: ["wellbore1"]}}  ) {    items {      space      data {        Oil {          1_day {            getDataPoints(start: 1672338600000, end: 2240591400000) {              items {                timestamp                value              }            }          }        }      }    }  }}we c

Hi all,I'm trying to increment my view version.To do this, I'm also incrementing my data model version as well.My original is```type Test @view(space: "test_space", version: "1_0"){    name: String!,    description: String,}```and I try to go to```type Test @view(space: "test_space", version: "1_1"){    name: String!,    description: String,    test_write: String}```I've also tried ```type Test @view(space: "test_space", version: "1_2"){    name: String!,    description: String,    test_write: String,    required_test_write: String!}```I get this error: {  "title": "Error: could not update data model",  "message": "An error has occured.

I am facing this error in the data science course on “creating cognite functions” with cognite SDK. In previous courses I had fixed this error by replacing the “datapoints” keyword with “time_series”. However, I would like to know if I am probably not using the write packages; OR not know if the commands are deprecated and have new function names in newer versions. Kindly let me know - I am trying to finish these courses before my local boot camp next week.Thanks,Lavanya

Hello,I’m encountering an issue with accessing a dataset on Cognite Jupyter Notebooks. According to this link: Jupyter Notebook in Cognite Data Fusion | Cognite Documentation, subfolders will appear empty if I don’t have access to the dataset. However, I can see the dataset through the data model corresponding to that dataset, but I still can't see any contents inside the subfolders.Do I need anotther type of access or is it another issue? Any help would be much appreciated.Thanks!

Hey guys. I’m trying to create a function with some different constants. Do you know how can I change the name of the constants? 

Hi,I have some questions on Cognite. Would you please help?1. Files1.1 To delete Cognite files, after deleting the files do we need to delete the documents also? 1.2 After we create the files, the documents are created by Cognite automatically, but it seems there are some random delay to create the document, why?1.3 what is the concept of document in Cognite? Why is it created? Any documents on that?2. sequences2.1 To delete Cognite sequences, after deleting the sequences do we need to delete the datapoints also? 3. timeseries3.1 To delete Cognite timeseries, after deleting the timeseries do we need to delete the datapoints also?4. delete order for containers, views 4.1 to delete all FDM data in a space, the order of deletion should be edges, nodes, containers, view versions, data models, space. And the containers should be deleted first then delete the view versions, right?Thank you!Alice

Dear community,We have been working with Python SDK developing functions and everything works fine, as expected.Now we have an IP development that has C# as base language. We need to call some of the Cognite Functions utilizing the .net SDK (https://github.com/cognitedata/cognite-sdk-dotnet)  but we are having troubles to call the functions trough .net.Has anyone been able to utilize Cognite Functions trough the .net SDK?Thank you all.Here is a snippet of the code: 

I am trying to create a Data Model in the UI. I can click ‘create data model’, name it, and land on the page with the editor and the pre commented pump/facility/documenation example. However I am not able to edit the graphql as anytime I try to edit in the editor I am told that I ‘cannot edit in read-only editor. Where is the toggle to disable the read-only editor?

After how much time retry of function get triggered on failing?Is there a way we can set the time to retrigger the function after function fails. It will be helpful to deal with rate limit in functions if any.

Hello,I’m trying to consume data from FDM in Power BI. But I’m getting error (408) Request Timeout. I’m already filtering Power BI for only a few days of data, which brings an amount of data comparable to the amounts I have already consumed in Power BI. How can I solve it?

What access capabilities do I need to run transformations as “Current User”. I have a user who don’t see “Run as current user” as in screen shot. Next screen shot is mine, and I can see it probably because I am added as admin 

Hi, Is it possible to use multiple clients for the same Cognite Function? I know the handle function only takes one client as argument, but is it possible to initialize another client inside the function? I want my Cognite function to read from prod environment, but write to dev environment, which necessitates two clients. Thanks.
