Hello Community,

my workflow (started from PowerApps) worked fine for a few months.

Suddenly a "call subflow" action throws a 401 "The workflow '<id>' could not be found." with error code 65.

Saving a copy of my subflow didn't solve the issue. I also created a new subflow as a test, with this I receive the same error.

Starting my subflow individual works fine.

Any suggestions?

Thank you in advance,

Sven

I have the same problem. Last week everything works fine, but today I get the error message when I try to edit the child flow.

The Flow name shown in the message does not exists in the environment.

Request to XRM API failed with error: 'Message: Flow client error returned with status code "Unauthorized" and details "{"error":{"code":"FlowNotOriginalAuthor","message":"The flow '68660d44-2dc8-123e-3eed-c7eefda07fee' is shared. Only the original author can perform management operations on the flow."}}". Code: 0x80060467 InnerError: '.

The flow has only one Owner and was never shared with anyone else.

meanwhile I found the following: My error throws a "The workflow '9308eac933b4471eb58ce1a3f010d369' could not be found" whereas my subflow has the id 58a1b6bf-a8f3-cb4d-d542-fb8b5bbde224. Is there any possibility that PA is mixing up my flow ids?

@ronaldwalcott thank you for your advice. Unfortunately this doesn't help out.

To try another test I built a completely new flow and added a subflow with noting but a "1" variable, but I also get a "The workflow xyz could not be found" error.

Sounds like an authorization issue. Did you say that you removed it from Power Apps the re-added it and it still did not work?

I have the same issue. I turned off the flow and it's not possible to turn on now.

I get this error message, which is nonsense. The original author is logged in.
Flow client error returned with status code "Unauthorized" and details "{"error":{"code":"FlowNotOriginalAuthor","message":"The flow '96a0dacd-acc8-c47e-9b55-a144329fd1fb' is shared. Only the original author can perform management operations on the flow."}}".
