I don't get how getTypedValue can return something which is not a string

Empty string on oracle is null?

See stack trace in linked issue. It is a string. Php would throw if it is not a string due to strict types.

I suspect a faulty PHP build being used on that machine.

Not Oracle, it's pgsql (as in the issue). The ): string hint is correct in the happy path, but the values returned come directly from $fastCache/$lazyCache, which are populated from PDO row data. The ?? '' in loadConfig guards against null, but doesn't cover all non-string cases that can end up in the cache from other write paths. The specific case here is user_ldap calling getValueBool($uid, 'user_ldap', 'isDeleted') on users who never had that key written, where a type mismatch in the stored metadata is enough to trigger it. PHP 8.4 made strtolower() fatal for non-strings (before that it was a silent deprecation), which is why this is only surfacing now. The stack trace in #59629 is from a stock PHP 8.4 build, reproduced by multiple people.

return in_array($b, ['1', 'true', 'yes', 'on']);
}
