I receive this error when trying to login via a github deployment preview url I get through Vercel. It works locally and in production but not on preview urls. I believe the issue to be related to my AUTH0_BASE_URL env variable along with the configuration in auth0.
For me, I would assume that the issue involves this env var being used for production on a preview url that isn’t the same domain but would love insight on to how this can be rectified.
For you others, my best advice would be to analyze the redirect_uri on the network request and confirm it is what it should be based on your specific environment as well as ensuring you have the correct env variable. I don’t know if that will help, just my guess based on my experience.
