Laravel 5 Model Factories Null Error

This is the error I am receiving when I try to use a Model factory for only my Message model. Other model factories are working just fine and I have tracked this down to the applyStates method in laravel's FactoryBuilder and it is in-fact null, I am just not sure why. I have the model class defined, I have the table created, the code in my method to add seed data for messages is working but this error is thrown after the first record is inserted keeping it from adding a bunch of seed data for me.

[2016-12-23 20:24:04] local.ERROR: Symfony\Component\Debug\Exception\FatalThrowableError: Type error: Argument 1 passed to Illuminate\Database\Eloquent\FactoryBuilder::applyStates() must be of the type array, null given, called in /Users/jcrawford/Dropbox/Work/RYNO/htdocs/vendor/laravel/framework/src/Illuminate/Database/Eloquent/FactoryBuilder.php on line 168 in /Users/jcrawford/Dropbox/Work/RYNO/htdocs/vendor/laravel/framework/src/Illuminate/Database/Eloquent/FactoryBuilder.php:180
