Signing up with an already existing username error is wrong / ambigous

I’ve created a username “testuser”, and I’m signing up again, specifically to test that a user cannot occupy the same user name. The error I get is “Something went wrong, please try again later”

I’m using sign in with redirect, via the react hooks.

It’s not clear as to what the error is. But from my admin dashboard > Monitoring > Logs,
we can see the proper errro, “The username provided is in use already”.

Why is this not being displayed on the frontend? and How can we make it so?

Bump on this, anyone have ideas?
