  4. Select the login button to go to http://phorge.localhost/auth/login/mediawiki:whatever/
[2023-08-04 18:08:10] EXCEPTION: (RuntimeException) strlen(): Passing null to parameter #1 ($string) of type string is deprecated at [<arcanist>/src/error/PhutilErrorHandler.php:261]

Fix that exception; get next exception in Arcanist due to ($this->tokenSecret) being null for some reason, not too be covered in this ticket / patch:
