Target [Illuminate\Contracts\Debug\ExceptionHandler] is not instantiable

I'm using Eloquent in combination with Slim Framework to build a small API. For some reason I am getting this error and I can't locate the problem:

Target [Illuminate\Contracts\Debug\ExceptionHandler] is not instantiable.

Database settings are correct. This error is thrown in my staging environment on the server. Locally, with MySQL 5.6.29, it works perfectly. Although I don't think it's related to MySQL 5.7 because I have another app running on the same server with the same version of Eloquent.

Can anyone point me in the right direction?

I'm using:

• Eloquent Version: 5.3.23
• PHP Version: 5.6.28
• Database Driver & Version: MySQL 5.7.16

I'm suspecting it has something to do with an unregistered error handler:

Buy how can I register the custom error handler when not using Laravel?
