520 Error : API Hub token exchange internal service failure

I have this flow that takes an attachment received via email and creates a new file on SharePoint . The flow works for smaller reports, but with a larger report I'm receiving (41MB) a 520 error. I receive this report daily, and would love to automate the publishing of the report to SharePoint. Has anyone resolved this issue? Thank you.

No solutions though. The Microsoft support 'solution' is to copy the workflow, which should work but is not acceptable.
