Fedora 38 machine with PHP 8.2.5. Just pulled Phorge; trying to set up a local Phorge test installation.
Trying to go to a workboard URL of any already existing/created workboard, like http://phorge.localhost/project/board/3/ (the DB and thus projects were still around from an older local Phabricator installation and thus not created in Phorge itself), and after working around T15262, I get:
```
Unhandled Exception ("RuntimeException"): rawurlencode(): Passing null to parameter #1 ($string) of type string is deprecated
```
triggered by
https://we.phorge.it/source/arcanist/browse/master/src/utils/utils.php$1891 containing
`return str_replace('%2F', '/', rawurlencode($string));`
=== Stacktrace, copied from T15313: ===
