I've spent days attempting to resolve this. Todate I've been unsuccessful. Most articles are probably out of date.
Testing with Postman absolutely no issue. Functions perfectly. Building swagger file and using this to create a Power App connector and total failure. I've had this working in the past without issue. When it comes to testing see images below. Tried running PowerApp and fails.

I deleted the previous connector.
I used Postman and imported the collection.
No authentication. Testing the connector and report suggests all is well. However issue appears ' Invalid number of arguments: recieved two expected five.
