A four digit year could not be found Data missing

have you tried using key value array in the create method:

factory(User::class)->create(['role_id' => 2]);

I might be late to the party, I was having the same problem and it turns out its because I provided a key without a value in the array returned.

get rid of 'provider' => ''.

As to the cause of the problem i really don't know but it has something to do with Carbon

php laravel laravel-seeding

I had the same issue when using mass assignment and it turned I had forgotten to wrap my array of inputs in the request helper function

That is I hadModel::create([form inputs]);

Instead ofModel::create(request([form inputs]);

Just incase someone comes across it.
