[Flask OAuth] User is not JSON serializable #17

Closed LorenzoCavatorta closed 5 years ago

LorenzoCavatorta commented 5 years ago

Hi,

I'm still working on the flask OAuth example. I'm currently able to give my user consent and get to the redirect; flask is throwing an error on Object of type User is not JSON serializable. FYI this is already including the two minor fixes I mention in the other two open issues, plus an added APP.secret_key on the flask program (required to be able to write/read from session)
