Hi,
Recently while trying to configure Topic Analysis in Dynamics 365
we got the below error for the failed record.
Error Message:{“code”:”BadRequest”,”message”:”Invalid request”,”innerError”:{“code”:”InvalidRequestContent”,”message”:”Requests to this API should contain at least 100 documents, where each document is not null or empty”,”minimumNumberOfDocuments”:100}}
This was because we had very few case records in our CRM organization < 30. We created few more records to increase the count to be more then 100 and re run the build. This time it got succeeded.
Hope it helps..
