Hi. I have a custom connector which has been working perfectly for over a month. It has 3 actions in it which get various results from Azure API's and I use them in a Power App.
Suddenly, all 3 actions are getting a 200 response but with blank response body and this schema Validation error:
Property "" type mismatch, Expected: "object", Actual: "string".
We have made no changes in both the Azure API's or custom connector.
The Azure API's are still producing the correct outputs in the correct formats and all my custom connector steps are successfully validated.
Tests from Postman work perfectly so the issue is within the Power Platform environment.
What do I need to look for? Has something changed in the custom connector environment on Power Platform?
