get_class() expects parameter 1 to be object, null given

[iredmedia]

I'm getting this error in one of my environments but I can't figure out why. It doesn't fail on home/login, but my internal pages it does.

get_class() expects parameter 1 to be object, null given

Here is more of the stack!

in Attachment.php (line 388)
--
at HandleExceptions->handleError(2, 'get_class() expects parameter 1 to be object, null given', '/app/vendor/codesleeve/stapler/src/Attachment.php', 388, array())
at get_class(null)in Attachment.php (line 388)
at Attachment->getInstanceClass()in Stapler.php (line 177)
at Stapler::getS3ClientInstance(object(Attachment))in Storage.php (line 27)

Edit: If i change the env FILESYSTEM_DRIVER to filesystem from S3 it works fine.

Most likely because one of your environments is PHP 7.2 and the other is not.

Note: Explicitly passing NULL as the object is no longer allowed as of PHP 7.2.0. The parameter is still optional and calling get_class() without a parameter from inside a class will work, but passing NULL now emits an E_WARNING notice.

Looks like this package will need an update to support PHP 7.2 and up.
