Custom-connector unauthorized

Basically I've started from a blank app and created a custom connector for a flow which triggers when an http-request happens.
This flow gets some query data and a file from the formData and creates a file (with metadata) in our sharepoint library. (see picture)image.png

I've fired the request multiple times in postman (application that helps you fire http requests) and everything worked as I wanted it to work. So then I decided to create a custom connector inside powerapps to allow me to fire the request with data from my app. There is not authentication and only 1 action described. Inside I set my sig, sp, sv, api-version to the values described in my flow's http request url.

Here are the contents of my open-api file (json) that I created using specgen: (some stuff is X'd out due to security reasons)

  }
}

 When I test my custom connector (either in powerapps or in the custom connector test tab) i get a 401 Response.

This is the request output:

And this is the response:image.png

 

 

This is the complete body but I didn't get much out of searching solutions for it:

 

{
  "error": {
    "code": "AuthorizationFailed",
    "message": "You do not have permissions to perform action 'run' on scope '/triggers/manual/paths/'. Verify you are making the request with the appropriate HTTP method. See http://aka.ms/logic-trigger for details."
  }
}

 If you need anything else , please let me know! 
Hopefully you can assist me Smiley Very Happy

Kind regards, Jan

Re: Custom-connector unauthorized

So you cannot even add the connector to Powerapps? Or did this error happen in flow?

Re: Custom-connector unauthorized

Any update here?  I am experiencing the same issue.  My logic app accepts a POST and the customer connection is configured as a POST.  I have the custom connector being called when I press a button, but PowerApps shows same error as mentioned above.

Re: Custom-connector unauthorized

It seems to be that powerapps has problems with certain open api configurations.
I got it to work after doing some adjustments , but I don't know what the problem was.

I suggest you try to get your custom connector to work using a postman collection. (v1)

Re: Custom-connector unauthorized

Use postman to form your request with all parameters possible and content body etc... based on that you can make a postman collection (v1) and create the custom connector based on that... There are guides on youtube and elsewhere on this
