Recently while trying to save one of our cloud flows having a “When a HTTP request is received” trigger, we got the below error message after adding the “List Rows” (Dataverse) action
Request to XRM API failed with error: ‘Message: Flow client error returned with status code “BadRequest” and details “{“error”:{“code”:”InvalidOpenApiFlow”,”message”:”Flow save failed with code ‘ValueNotSupported’ and message ‘The trigger ‘manual’ at line ‘1’ and column ‘835’ is not valid. The ‘operationOptions’ property is not allowed on the trigger when the workflow contains actions of type ‘OpenApiConnection’.’.”}}”. Code: 0x80060467 InnerError: ‘.

This error occurs when you try to enable the “Suppress Headers” or “Schema Validation” option for the “When a HTTP request is received” trigger while also using actions that connect to Open API (OpenApiConnection) services within the same flow. Seems like a current limitation in Power Automate. The workaround could be to create a separate child flow having the action associated with Open API Services and use these options in the Parent flow.

Hope it helps..
