Can't authenticate with commentpara.de: Missing element "scope" in authorization_endpoint response

[cweiske]

After #13 was fixed in commentpara.de, I have another issue.

I get an error:

04-23 18:20:50.507 12647 12647 E micropub: android.accounts.AuthenticatorException: Could not verify authorization: Missing element "scope" in authorization_endpoint response

It posts to https://commentpara.de/auth.php:

code=ZW1vamk9JTVDMzYwJTVDMjM3JTVDMjIyJTVDMjUxJm1lPWh0dHBzJTNBJTJGJTJGY29tbWVudHBhcmEuZGUlMkZ1c2VyJTJGMy5odG0mc2NvcGU9Y3JlYXRlK2VkaXQrdXBkYXRlK3Bvc3QrZGVsZXRlJnNpZ25hdHVyZT1GSVhNRQ%3D%3D
&redirect_uri=wrimini%3A%2F%2Foauth
&client_id=https%3A%2F%2Fstuifzand.eu%2Fmicropub

and gets in return:

{"me":"https:\/\/commentpara.de\/user\/3.htm"}

The spec says in "5.4 Authorization Code Verification"

If the request is valid, then the endpoint responds with a JSON [RFC7159] object containing one property, me, with the canonical user profile URL for the user who signed in.

It sounds like this app is trying to post to the authorization endpoint, but it should be posting to the token endpoint instead?

I uploaded a new version that fixes this problem. Can you try it?

I had found this problem as well. It was fixed in f9a1336

[aaronpk]

If this app is a Micropub client, it should be doing the authorization flow rather than the authentication flow.

https://indieauth.spec.indieweb.org/#authorization

In this flow, the client only makes a POST request to the token endpoint, not to the authorization endpoint.

This issue does not occur in Wrimini 0.0.10-alpha.
