When the module is enabled on a site running on PHP 8.1 (and likely 8.0) we run into a couple of PHP warnings:
Warning: Undefined array key "id" in /code/docroot/modules/contrib/newrelic_transactions/src/EventSubscriber/EventSubscriber.php on line 129
Warning: Undefined array key "roles" in /code/docroot/modules/contrib/newrelic_transactions/src/EventSubscriber/EventSubscriber.php on line 132
In retrospect these may just be because the config form has never been saved, but once I get past these errors. I encounter a WSOD:
The website encountered an unexpected error. Please try again later.
TypeError: method_exists(): Argument #1 ($object_or_class) must be of type object|string, int given in method_exists() (line 77 of modules/contrib/newrelic_transactions/src/EventSubscriber/EventSubscriber.php).

Fixed
1.0
Code
In retrospect, I think the undefined array index issue may have just been caused by not having saved the config form once, which also needed a fix, but the second issue stops the module from working on PHP 8.
Automatically closed - issue fixed for 2 weeks with no activity.
