Bubble login via AppGyver not working

I’ve been following this post https://seanhoots22.gitbook.io/tutorials/appgyver-3rd-party-authentication-with-bubble/setup-bubble-backend to use Bubble’s as an SSO for my Bubble user’s to log into a mobile app built with AppGyver. I’ve got this working in Postman, but when I replicate it in AppGyver, I’m getting Bubble’s 500 error:

Error: JSON error response from server: {“error_class”:“UnexpectedError”,“args”:{“code”:“1664224728058x822352692357488600”},“message”:“Sorry, we ran into a temporary bug and can’t complete your request. We’ll fix it as soon as we can; please try again in a bit!”}.status: 500

Anyone experience this before or have any thoughts on a fix?

Be sure that your bubble app is on the paid plan. The free one doesn’t have API option anymore.
