Strange Custom Connector Update Issue

Hello all, apologies if this isn't the correct place to post about Custom Connectors.


I have written a custom connector to wrap the web API for the application that my company has created.  I recently went to update the connector in our dev environment by uploading an updated OpenAPI file and received the following error:



The request failed with error: '
    "Message":"PUT failed with BadRequest, 
            \"message\":\"One or more fields contain incorrect values:\",
                    \"message\":\"Invalid identifier cosmos.20forms.5f20c43aa1189e0005.5f2c3313837e7254f6 specified.  Entity Identifier can contain only letters, numbers, and hyphens. The first and last character must be a letter or a number \"
The tracking Id is '71eec2da-0c24-4fbf-8ba2-2de6b2e521fd'.



I downloaded a copy of the connector after receiving the error and my changes were there.  I also created a new connector using the same OpenAPI file and that worked fine.


I've searched the web and couldn't find anything that referred to Entity identifier's and Power Automate or Flow.


Any thoughts on what the error might be referring to?

Ran into the same problem today.


I had something similar one time when a custom connector wasn't used for some time, it turned itself off. The issue I have now is also with a connector, that wasn't in use for a while.


Will investigate some more...

Have you identified any solution for this? Getting same issue.

I ended up deleting the connector (after I copied the "code"), recreating it and updating the apps and flows to use the new one. It's done in a few minutes and can be done without breaking anything 8work depends a little on how many apps and flow you have using this connector).
