I recently upgraded to PHP v8.4.5 and got an error when trying to post msgs using
chatPostMessage()
.Error message was:
SlackPhp\\BlockKit\\Kit::file(): Implicitly marking parameter $externalId as nullable is deprecated, the explicit nullable type must be used instead
I think the fix is to change line 123 in Kit.php from:
string $externalId = null,
to:
?string $externalId = null,
I realize this may only be one of many issues related to PHP v4.4 compatibility, but this is the one that I ran into.
