Custom connector works in testing but not in flow.

[nothankyou000]

Hello,

I recently built a custom connector, it works when tested, but when I try to use it in Power Automate I get this error:

Here is the swagger:

I was wondering if someone may have an idea on why I keep getting this error.

Thank you.

Hi there,

Unfortunately, there is currently a bug in the test connectors page where it will accept a string as an object.  To fix the error in Flow, you will need to make your response an object in swagger.
