Dataverse AI Builder Predict Action Timeout

(0) ShareShare
ReportReport
Posted on by MA-09051453-0 12
Hi,

I am facing intermittent timeout issues with AI Builder Predict actions in Power Automate and would like to check if anyone else has experienced similar behavior recently.

Issue details:

  • Using AI Builder Invoice Processing model
  • Flow was working fine previously without any major changes
  • Small PDF invoices are also failing (1 page test files)
  • Predict action keeps retrying and eventually fails with RequestTimeout / 408 timeout
  • Some runs retry for hours before failing
  • Both old Dataverse Predict action and newer Predict by record ID action tested

Errors received:

  • RequestTimeout
  • “A timeout has occurred while sending a message to the backend”
  • Status Code: 408

What I already tested:

  • Small/simple PDFs
  • request v1 and requestv2 payload formats
  • Different Predict connectors/actions
  • MIME type validation
  • Base64 content validation

Any help would be appreciated. Thanks in advance!

    Hi

     

    This could be related to a known AI Builder issue that occurred between May 8 and May 11 and was resolved yesterday.

     

    It should now be working normally again.

    Let me know!
