Hey I'm new to Xano and i'm trying to set up a test site to figure out how to introduce users into a webflow site. I followed the instructions from the 'Enable your Webflow users to log in with Google using Xano' video. I've gone over everything a million times and I can't figure out why im getting this error message. Sometimes it returns error 500, other it returns error 403. Has anyone else had this same issue or managed to resolve it?
