Same problem.

Seems like when you try to install passport using mongodb passport doesn't know what to do.

This solved my problem https://github.com/sadnub/laravel-mongodb-passport-fix

[sedrak1987]

use my package for mongodb(based to Laravel passport, so you can use Passport doc)
https://packagist.org/packages/sedrak/laravel-mongodb-passport
remove larvel passport from composer and install this.
