Invalid backend when converting token on server

[crozarakamilla]

Hey there! First of all thank you for keeping this project alive.

I've been struggling a little bit to get things working on the server. When running locally it works like a charm:

But when I try to do the same on the server (over https) I'm getting the Invalid backend parameter error:

It's the same error if I try with facebook or google-oauth2 backends.

Here are the configs:

Have you ever had this issue? Do you have a clue about it? I'm very confused about this because it was supposed to work just fine since it is working when I am running locally.

Hi @crozarakamilla. Thank you.

I have seen this error before. I realised it was because I didn't have an Application called facebook in production. Can you cehck that please?

[crozarakamilla]

Thank your for your answer.

You mean the DJANGO OAUTH TOOLKIT's Application?

I've changed the name, but still the same error:

[wagnerdelima]

Seems a bit exoteric to me. My apps work either locally or for production purposes.

What is that algorithm section No OICD support? I don't have that included. Is this from latest versions of your social python?

What are the versions of your oauth2_provider and social_django you are using?

[crozarakamilla]

Hey there! Here are the versions I am using on my project:

django-oauth-toolkit==1.5.0 social-auth-app-django==4.0.0 social-auth-core==4.1.0 oauthlib==3.1.0 drf-social-oauth2==1.0.9

It's the first time I am using this package and I just left this OICD support as default.

@wagnerdelima Similarly I am resulting the same issue where the settings are all fine but the response return as invalid backend

[wagnerdelima]

@crozarakamilla and @timothyshen

Did you manage to overcome this situation?

[wagnerdelima]

@crozarakamilla and @timothyshen did you manage to get it to work?
