Hi @Madina Kholmatova and CDF Academy Instructors,

I am glad to have completed this (CDF Fundamentals) course.

Thank you very much for your very prompt and able support thru out this course. 

Kind regards,

Hello,

I´m having trouble finding my data set in the “Select Entities” tab during the “Match Entities” module. I have already created a new IFSDB data set, but I can´t find either of them in the search.

Hi @Mayara Chinaglia 

 

This is a known issue that we are experiencing with the training project and I am sorry that you are experiencing this issue. 

Entity matching can filter a limited number of datasets. Since we have a lot of datasets (currently, there are 1921 datasets in the project), the matcher is not able to go through all the existing datasets. 

We have reported the issue to our engineering team. Unfortunately, you will need to skip this part or build your dataset from scratch.

Could you please also mention the name of your dataset so that we can report it to our engineering team as well?

 

Best regards,
Dilini

Hi, @Dilini Fernando 

Thank you for your quick answer. I´ve read this previous issue here in the discussion and tried to create a new data set, but even this way I wasn´t able to find them. The data sets are called “Mayara1997-IFSDB” and “Mayara1997-IFSDB1”

Hi @Mayara Chinaglia

Thanks for letting us know. I’ve informed our engineering team that you reported this issue as well. For now you’ll unfortunately have to skip this part. I’m sorry it’s currently not working.

@Dilini Fernando  I too have the same issue and my Dataset ID is NV1991-IFSDB.

Hi all!!

I'm running a model and task 3 is 20% for the last 2 hs. After several page refresh it's the same. Any other work around to advance with teh CDF fundamentela trainig? Thanks in advance!!

 

Same for diagram models

Hi @Alejandro M. Toledano

I am sorry that you are experiencing this issue. I have also tried from end and it seems there is an issue in the backend in this training project. I will create a ticket, and our Cognite support team will reach out to you!

Hi @Alejandro M. Toledano

I’m Viraj here from Cognite Support and I'm sorry to inform you that currently we are facing a Major Incident impacting Contextualization Service (Entity matching and Engineering diagram) and it is very likely be the root cause of your issue. 

As the engineering team is working to solve the issue, I will follow up and update you with the latest information when available. 

Sorry for the all inconvenience made via this Incident. 

 

Best regards, 

Viraj

Hi @Alejandro M. Toledano

 

It’s Viraj here again and the engineering team has made a fix to the Major Incident. 

Can you please try again and let us know whether it works for you or not?

I am running into issues in trying to create an interactive engineering diagram. When I look for the assets data set, I cannot search for it. I can’t type into the search near the magnifying glass and when I read through all of the options, my data set was not there. Even with “select all” - only 303 data sets come through and mine is not one of them.

Hi @Kiona,

I’m creating a ticket for Support out of this, it looks like we can reproduce the same issue, and we’ll need to look into this further.

Datasets I create cannot be searched or found.  Therefore I’m unable to build the transform as I cannot find the dataset to look for it’s dataset ID. I’ve tested this various ways, creating and deleting various data sets.  They are uanble to found in the general search and do not show up in drop downs like are available when creating a Transform.  Kind of stuck at this point.

Hi Jason,

Thanks for reaching out, I’ve created a Support ticket for this to further investigate, since I think we’ll need some more details from you.

Hello all,

SQL statement for Events did not find records since all completion_time=start_time in maintenance table of IFSDB, so I modified ‘>’ to ‘>=’ in the WHERE clause but only get 8 records instead of the 18. Will this be a problem for my Contextualization and later modules?

I experienced the same issue and also made the same changes to the query.

Thank you so much @Dirk Ackerman  and @Terry Gansen for notifying us, and even finding a solution for it! The course is updated! :D

I am not able to see all events transform data in my data set. The query change which @Dirk Ackerman suggested is showing only 8 events in the dataset. Please suggest

Hi @Akshit Joshi! I took a close look at the raw table and transformation and I found out that someone has tempered with the maintenance table in RAW. @Dirk Ackerman  and @Terry Gansen fix, helped a little bit. But now the table is back to the original condition and all of you should be able to create all the events.

Hi! I’m working through the CDF Fundamentals learning path and came across a bug with the bonus time series transformation exercise in the Working With CDF: Contextualize course. I used the SQL statement as it was provided and the preview resulted in 984 rows, but it correctly saved only 12 records when I ran the transformation. The issue I noticed is when I followed the entity matching for the time series records and got a message that it was going to overwrite all the asset ids for the 12 records. 

After further review, it looks like the transformation query ran the metadata function for everyone’s test data in the system (the HashMap function shows externalIds for several/all users test data), and the asset id that was saved did not correspond to my data.

I was able to add a where clause to resolve the transformation and get the correct asset id’s in the result. Screenshots of each dataset attached for reference.
