This is how I expected rule errors to work (just a mockup):
But looks like this is not supported (related Custom error in rules in Auth0 - HOW TO )
It’s a bit confusing since there are docs that suggest it could be supported (like Customize Lock Error Messages for Lock, not UL).
Also, looks like errors in rules always redirect to the default callback url, not to the generic/custom error page. At least a hash with error_description is appended to the callback. Therefore, the only thing I can do is handle that hash in my callback url and redirect to a custom page to handle it.
@dan.woda Please let me know if anything I said is wrong.
