gomniauth: Parameter 'code' is required but missing. (Facebook provider)

[oleksandr]

When pressing Cancel at the Facebook page the following error is shown:
gomniauth: Parameter 'code' is required but missing.

The callback URL is the following:
http://localhost:8080/oauth2/callback/facebook?error=access_denied&error_code=200&error_description=Permissions+error&error_reason=user_denied&state=..........

I guess Facebook simply renamed parameters?

It's because that's an error response. You shouldn't call HandleCallback if an error is returned. You should do something else.

Make sense?

@matryer to me, as a beginner, what you said makes little sense. What is the proper way to handle callback? I am looking at the sample application: https://github.com/stretchr/gomniauth/blob/master/example/goweb/main.go#L102 and I have no idea how to properly check if this is an error response. Should I manually parse the query string at this point before I call CompleteAuth?
