Collection Already Exists Runtime Exception

[wayne5w]

I've got some simple schema create code that runs fine on the old 2.x driver. I recently moved to php 7 and the 3.x driver and now I am getting a Collection Already Exists runtime exception (below). The collection does not exist. Did something change/break?

Here is the code

       Schema::connection('mongodb')->create('virtual_version', function($collection) {
                $collection->index('id');
                $collection->index('client_id');
                ;
            });

Actually this is not the problem, need to investigate more. Something has changed, not sure what.

@wayne5w i got the same issue with Laravel 5.5.* and mongo 3.4.*

add this code on your "down" method:

Schema::connection("mongodb")->dropIfExists('establishments');
