Hi all - I’m new to CDF.I’d like to call CDF from JavaScript running in a browser using a bearer token as authentication.This request works fine when made from a tool such as Postman, but when the same call is made from JavaScript running in a browser using the same URL and bearer token, the browser’s CORS policy blocks the request because CDF has not responded to the preflight OPTIONS request with the HTTP header Access-Control-Allow-Credentials: trueApart from this, CDF is correctly sending out all the other HTTP headers needed to satisfy the browser’s CORS policy such asAccess-Control-Allow-HeadersAccess-Control-Allow-MethodsAccess-Control-Allow-OriginAccess-Control-Expose-HeadersAccess-Control-Max-AgeWhere do I configure CDF to respond with this additional HTTP header?Thanks  

I have to build two 2 types of extractors.1. PI extractor to connect to the PI server and fetch the data and ingest into CDF2. SharePoint online - Extract data from files present in SharePoint online and ingest into CDF. I wanted to know the construct in building the extractors. Mainly wanted to account for scenarios where the PI server is not available and PI extractor is unable to fetch the data from the pipeline. How to handle these kinds of situations and incorporate them in the code while building the extractor. Also, how to handle monitoring while performing extractor. Are there some sample code repos that can be referenced for getting complete idea for building extractors.    

Is it possible to gain access to the Github repo for the InDSL? I will use Charts in my work, and would like to be able to contribute to the development.

We have a unique use case where there are data points collected from PI server for refinery plant and alongside, we have other refinery data like Crude assays, Diet, Mass Balance. All these data points (in tabular format) are collected and then some formula is applied across to get properties (like swing cut %, CBLISS, Vol%, etc.) and some derived tables are created. Then some input feed is made from the actual data sent to a Petro-Sim tool (math simulation tool/modeling) and then output from that tool is collected and stored. All these data wrangling is done and finally charts are finally made for some 50+ crude product variants to measure yield tracking (Actual data, non-linear model data, linear model data). As per design, we are planning to use the CDF raw tables and then do all the computations and create derived raw tables to fulfil the purpose. Then use Petro-Sim connector and then store the data output from the model tool as well in raw tables. So, we don't tend to see the typi

Do we have any api in cognite which will help to show preview data of transformations?

I am currently working through “Learn to Use the Cognite Python SDK”. I am unsure where the workspace/code is provided so that I am able to take the final the test and succeed in this course. I was originally using a colab research google file that includes prompts. But the questions on the final test did not corelate with this file. Can you please instruct me on how I find the correct files/workspace.  Thank you in advance. 

Hi all, I ran into an error when running a transform: instances failed with status 400: Request had 37 constraint violations. Please fix the request and try again.

Hello May I know if inventor 3D model is supported in CDF? 

I noticed that calling a pre-existing Cognite Function requires the functionsAcl:WRITE capability. Essentially this means that I cannot make a function available to users/dashboards/applications without simultaneously giving them permission to delete functions. What is the reccommended pattern for ACL when making Cognite Functions that are to be called by others?https://docs.cognite.com/api/v1/#tag/Function-calls

hello Community,While logging into cognite infield, there is a option to sign in with project name.so that project name is the project created in CDF?in documentation, we can see Infield runs on CDF, Which means CDF project is only way to get data into infield? or any other ways we can get data into infield?is there way to access infield from python sdk?Thank you

We multiple are seeing 408 response code from graphql query api. There are multiple combinations of filters which are not working. For eg the below one returns 408, i think the problem is with the array length of filter entity.entityName. If the array length is 2 it works else it is not working.query MyQuery {          listTimeSeriesRef(filter:{and:[{entity:{entityType:{in:["NAVIGATOR","SCREEN_CFG_REF"]}}},{property:{in:["TUBING_TEMP"]}},{entity:{entityName:{in:["Process.ReAllocation","Analysis Point by Desks","Downtime.GroupDowntime.DateTime.Subsystem"]}}}]}) {            edges {              node {                property        entity{        lastUpdated        entityType        entityName        }              }            }          }        }

HI All, I am looking to help in order to display timeseries and events co-relation in Power BI. I want to show when the event occurred in timeseries chart on specific event time.Any inputs would be appreciated! Regards,Arati 

Hi. I’m trying to understand why no alert has been triggered for the following monitoring job.Am I right to understand that this monitoring job should trigger an alert when the time series is above the specified threshold? (I am a bit confused by the text “alert when the threshold is”. Is this perhaps not monitoring the time series itself, but a threshold specified on the threshold tab?) 

Hi Team, I am trying to use bootstrap-cli to create raw DB, CDF groups and datasets. As per the documentation, I am executing “bootstrap-cli prepare” command before applying “bootstrap-cli deploy”.

Hi Team, Please enable and configure Air setup in the below CDF project. (Accenture-demo-dev) under cluster EUROPE1-GOOGLE. Please let me know for any details. 

We are having performance issues for event retrieval whenever there are more events even below 500.Can you help me to understand how partitioning can be done or pagination, as we need to perform operation for each event after retrieval and send it as a api response.I tried below:  for unstructre_insight in client.events(type="Insight", limit=None,partitions=10):     (“do something with unstructre_insight in each partition in parallel to reduce response time”)I observed that if there are 64 events, then all 64 events are retrieved in one execution, how we can get one partition at a time and perform something for first partition in parallel while retrieving second partition to reduce time.

Are ANSI escape sequences planned to be added to the Cognite Function logs? For now, it seems to be impossible to make the text bold or change the color of the text inside the function logs. 

Hi, There are raw data files which are used to perform computations (yield tracking measures ) that uses tons of input data attributes to compute the metrics. Currently, VBA macros (excel) is used to perform the calculations and publishing the outputs. WE have to transfer the computation within CDF. Can we use cognite functions in this regard?. Is there a way to create python script that can perform these calculations within the CDF. If not, should we create some external cloud based construct like Azure functions or Lambda routines?Please share some examples are snippets that can help to perform this project task.

I have been using RAW tables and creating a final table out. After creating a transformation, I could see the number of rows as ~8000 but that's a wrong number. After changing the transformation a bit, now I got the correct number post running the transformation which  is around 4000 but the final RAW table isn't changing.I could see that the table isn't being overridden with the new data. Can anyone explain me why? Thanks in advance!
