Power Automate errors / Schema
InvalidRequestContent. The request content was invalid and could not be deserialized.
Cause
A required field in the action payload (commonly the approval assignedTo, or an attachment property) is null or uses an incorrect property name.
Fix
Check the run detail to see which field is null/malformed. For approvals, ensure Assigned To has a valid user email and is never blank. For attachments, use the content property formatted as {"name": "<file>", "content": "<base64>"}. Re-run after fixing the payload.
