Can't register new account in Spark

I've setup a new Laravel Spark instance and haven't changed anything about it, it's exactly like it is out of the box. I'm trying to register a new account and I'm getting the following error:

Something went wrong. Please try again or contact customer support.

When I run php artisan migrate I'm getting the following errors in Terminal:

[Illuminate\Database\QueryException]

Where am I going wrong?
