Issue following blog post on NestJS setup

I’m working through this blog and ran into an issue with the login prompt that I didn’t see mentioned in the blog topic which is now closed.

The first issue was
unauthorized_client: Callback URL mismatch. https://dashboard.whatabyte.now.sh/home is not in the list of allowed callback URLs

The blog only says to set Allowed Callback URLs to https://dashboard-v1.whatabyte.app/home but I also added https://dashboard.whatabyte.now.sh/home. I also needed to add https://dashboard.whatabyte.now.sh to the Allowed Web Origins.

Finally I was able to create an account, but then when attempting to login the popup is blank, and upon viewing browser (firefox) console I see Failed to execute ‘postMessage’ on ‘DOMWindow’: The target origin provided (‘https://dashboard.whatabyte.now.sh’) does not match the recipient window’s origin (‘https://dashboard-v1.whatabyte.app’).

I’m not sure what to do at this point.

@dan-auth0 Do you have any idea what could be causing the second error?
