API Connector Error: Request path contains unescaped characters

Hey everyone,

I’m trying to set up an OAuth2 login/signup.

I filled out everything needed in the API Connector plugin form, created the “Signup/login with a social network” action that sends the user to the authorization page, and then ran it with debug_mode=true to initalize the API.

After I authorized the app to gain access to my account with the service and the service redirected me back to the app with the necessary data, I got this error message in Bubble:

When I looked at what the service sends back to Bubble, it all looked good to me, with the characters properly URL-encoded.

Anyone has any idea what’s going on there?
