Hello,

I just upgraded Laravel 5.7 to 5.8 and now I'm getting the following error whenever loading the site as well as in the terminal.

Warning: array_key_exists(): The first argument should be either a string or an integer in {redacted local path}\vendor\vlucas\phpdotenv\src\Environment\Adapter\EnvConstAdapter.php on line 29

Warning: array_key_exists(): The first argument should be either a string or an integer in {redacted local path}\vendor\vlucas\phpdotenv\src\Environment\Adapter\ServerConstAdapter.php on line 29

Not sure if this is helpful, but when I print_r($name) just before line 29 on these files here is the output.

It looks like you are calling env(null) somewhere, which is causing this warning. I might update the codebase to throw an exception so you can see a full stacktrace.

@westernstatesflooring Please try with #351. This should show you were your bad function call is.

#351 created the exception report, found the stupid error in one of my config files. Thank you so much!
