OAuth2::AccessToken#refresh! "NoMethodError: undefined method `options=' for nil:NilClass"

Created by: kharamel

I modified refresh token to be invalid and refresh! is throwing this (NoMethodError: undefined method options=' for nil:NilClass) error. Is it possible to throw a more semantic error similar to raise('refresh_token is not valid')? This way we can catch the error on our end and handle it accordingly.

Notes:

• access token is expired.
• refresh token is not expired.
• refresh token is invalid.
