How could we help you?
I am using Laravel/Lumen v5.8, yes very far behind, but that's what it is.
this package's CloudFront::invalidate() fails at line 33 of CloudFrontManager. There is no $this->config[] in Illuminate\Support\Manager. But if line 33 is changed from
$config = $this->config['cloudfront'];
to
$config = config('cloudfront');
using the helper function, it works fine. Could it be just the difference between Laravel and Lumen?
