"There was a problem creating your knowledge source" at file upload to GenAI sources of chatbot

Posted on by 6


I hope I am posting to the correct forum this time.

I need help.

I have a copilot studio chat bot I have created on Feb 2024 in copilot studio.

It has been / is working fine with Generative AI sources (4 public websites, and a couple of PDF, XLS files).

Now I am trying to add a new excel file to the new interface "Knowledge Source" and having the following error message:

I have tried to upload the same file on another test copilot chat bot, and it worked fine. So the issue is not the file.

I also tried to upload the excel content to a Dataverse table, and to use the corresponding add knowledge source, and also had issues. The dataverse table is now in the list, but the status of the table is set to Unkown:

What can I do to solve this issue??

Any help will be much appreciated.
