Comment (by TobiasBg):

 Hi @lenasterg,

 thanks for looking into this!

 When getting this deprecation warning, can you see where that `null` value
 is coming from?
 A password should only ever be a string, so it might make more sense to
 add a fix to the calling function.
 With the suggested `is_string()` check, the issue is essentially just
 shifted further down, when the next operation on the still-`null`
 `$password` happens -- but then this check might just make debugging and
 finding the origin a bit harder.
