put the full stack trace.

probably the reason is you're trying to cache (store) a closure, closures cannot be serialized.

I'm pretty sure the SuperClosure package allows closures to be serialized (although I have no idea what that really means).

FatalErrorException in SerializableClosure.php line 117: Uncaught exception 'ErrorException' with message 'Serialization of closure failed: Serialization of 'Closure' is not allowed' in /Users/me/Data/Solutions/site.local/site.live/vendor/jeremeamia/SuperClosure/src/SerializableClosure.php:117

That's all it shows.

This is still happening. Laravel used to throw helpful errors, but it doesn't anymore. Why?

This it the code that seems to be causing the issue at the moment:

$response = $kernel->handle(
    $request = Illuminate\Http\Request::capture()
);

However, every exception throws that except same message. Makes things very hard to troubleshoot.
