Signup confirmation email link buggy on second click

Bug report

Describe the bug

if I click the account confirmation link again after confirming, I get an ugly JSON 404 response. Since this is user facing, it can be confusing. The JSON response looks like this {"code":404,"msg":"User not found"}.

To Reproduce

Steps to reproduce the behavior, please provide code snippets or a repository:

1. signup as a user of a supabase app (triggered by supabase.auth.signup())
2. open confirmation email and click the link, and find yourself in the app as expected
3. go back to mailbox and click the link again (say I forgot if I clicked it or not)
4. end up on the error message above

Expected behavior

A proper HTML page with a meaningful message would be better. Maybe “you’ve already confirmed your account”?

What is the status on this? The PRs mentioned above were merged but it still happens.

understand

double clicking to confirm it returns the error.

{"code":404,"msg":"User not found"}

@kiwicopple . can we make a lake to deal with this error?

** if the token does not exist, just redirect to the site
