The given key was not present in the dictionary

Hi, I am trying my Save my changes after Transform Data, and I’m getting this error. I am connecting to a Teradata source, and I was not getting this before, does it have to do with my queries, or something else?
How can I fix it?

Thanks!

  • Use the proper category that best describes your topic
  • Provide as much context to a question as possible.
  • Include the masked demo pbix file, images of the entire scenario you are dealing with, screenshot of the data model, details of how you want to visualize a result, and any other supporting links and details.

I also suggest that you check the forum guideline How To Use The Enterprise DNA Support Forum. Not adhering to it may sometimes cause delay in getting an answer.

Please also check the How To Mask Sensitive Data thread for some tips on how to mask your pbix file.
