Welcome to the CDF Fundamentals Discussion!

This discussion is dedicated to help learners of the Cognite Data Fusion Fundamentals learning path succeed. If you’re struggling with the exercises in this learning path, try the tips & tricks below or post a comment with the challenge you’re facing. You can also post your own tips and respond to fellow learners’ questions. Cognite Academy’s instructors are also here to help.

 

 

Some tips:

  1. turn off blockers in your browsers (if you have any)
  2. “network issue”… yess, the system is overloaded … refresh & try again, and again ;-)
  3. you see “selected recipe is invalid...” message? Your preview failed (98% network issue). Try again, or just go ahead.
  4. “failed to lock this transform” message? probably the transform is finished (check the dataset) if not, run it again. ,yes, the same network/overload issue]

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 again @Ikechi Vera Maduako,

There was missing a colon (:) in your query. I just fixed, and run your transformation successfully.

@rahul331 for some reason it is working now for me! I think this has been just fixed! Thank you though :) 


Hello,

For the Data points step “Transform RAW to Data points” I received the error “Query returned no results. The query is syntactically correct, but returned 0 rows of data.” 

It seems the query does not filter for dataSetId and returns no matches. I changed the query to solve the issue on my end, here are the changes: 

SELECT
  concat('FirstnameBirthyear:',dp.sensor) AS externalId,
  cast(time_stamp/1000 as timestamp) AS timestamp,
  cast(value AS double)
FROM IFSDB.values AS dp
JOIN _cdf.timeseries AS ts 
ON CONCAT('FirstnameBirthyear:', dp.sensor) = ts.externalId
AND ts.dataSetId = '1234567890'


I realized my mistake, I need to replace Matt1996-AvevaNet with my dataset ID that was recorded earlier. Problem solved :)


Hi ​@LEIDY JOHANNA CAMPOS QUESADA 

According to the error message, it is complaining about the Data Set Id. 
If I go into Data Catalog and search for your data set, I find it with ID 3665583308625309. Which is not the same ID as you used in the SQL Query. I think if you replace it, it will work!

Link to your data set:  https://cognite-learn.fusion.cognite.com/cdf-fundamentals/data-catalog/data-set/3665583308625309?cluster=api.cognitedata.com&workspace=data-management

Hi @Mahmoud Shihab,

Thank you for reaching out regarding the issue! I will investigate it and get back to you as soon as possible.

Best regards,

No worries at all! We are happy that you could proceed with the SQL option and congratulations on your completion. 

Yes, please let us know if you experience the issue again whenever you have time to try it out. 

Best regards,
Madina


Hi @Deepali Gupta

I am sorry that you are experiencing this issue. Please don't delete your Deepali1996-IFSDB yet, in the meanwhile, you can  create & build another dataset (with a different name). I will try to investigate the issue and get back to you as soon as possible. 

​​​​​​@Mahmoud Shihab, thank you very much for the help!

Best regards,
Madina


Hi, I get the following error message when trying to access the create interactive engineering diagrams function, what has gone wrong.

 


Hi @Pernille Ronæss Melleby

Thank you for reaching out! I see that you have already completed your transformations, so you should have all the capabilities. Can you please log out and log in again? If it doesn’t work, can you also try it in Incognito mode? 

Let us know if you are able to proceed! 

Best regards,
Madina


Hi,

I’m getting the following error when I tried to open Interactive Engineering Diagrams. Anyone please help me regarding what should be done. 

 


Hi @Sai Srinija and @raul.mota

We are investigating the issue and we will get back to you as soon as possible!

Thank you!

Hi there,

I have trouble in "Working with CDF: Contextualize" “Quick Match” module. When I tried to match time series to assets, I can select my HQ1973-IFSDB dataset in “Select entities” Tag, but I cannot find my asset dataset HQ1973-AvevaNet in “Select assets” Tag.

Would you please help look into my issue?

Best Regards,

Qing

 

Please ignore my post above, as my problem solved after I re-login with Microsoft Edge in “InPrivate” mode.

Best Regards,

Qing


Hi @Sai Srinija, @John Ivey and @qhua

I have given the annotations:write capabilities. Can you please log out and log in again, would be better if you can also try it in incognito mode? 

Let me know if the issue is resolved!

Best regards,
Madina


Hi @Pernille Ronæss Melleby

I see that you have completed the learning path, and congratulations on that! Has the issue been resolved for you?

Best regards,
Madina


Hi @Anindya Ray

If you would like to follow the naming convention as instructed in the course, the database name should be FirstnameBirthyear and the table name just assets. 

If you can please redo this lesson with database name as Ray1968 and table name as assets, then the SQL code you entered should work. 

Please let me know if it works! 

Best regards,
Madina


Hi @Madina Kholmatova ,

Many thanks for writing back. 

I will redo this lesson as you have suggested with:

Database: Ray1968

Table: assets

Should I leave the earlier created 

Database: Rayassets

Data Table: Rayassets1968

as it is or delete it.

 

Let me know please.

Thanks,

Anindya Ray 


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,

Anindya Ray


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 @Naveen V, thank you for reporting. I’ve informed engineering of your details as well. We’ll keep you updated on the progress. 


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! 

Best regards, 
Madina


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

Hi, I’m in the CDF-fundamentals last course “Working with CDF: Consume” but when I click on “+ New chart” I get a “busy” screen that goes on endlessly.  

Is there something wrong with this?  Have tried different browser types (MS Edge, Chrome), refreshed/reloaded page, removed pop-up blockers, anything I’ve come across in the tip notes but nothing seems to be working.
When I back out “← All charts” it seems the new chart has been created, but when I click the preview icon
I get the same busy screen again.

My data is all starting with Daniel1969.  Thanks for checking.

Best Regards,

Danny
