I upgraded Lumen from 5.7.* to 5.8 followed by methods from official documentation

https://lumen.laravel.com/docs/5.8/upgrade#upgrade-5.8.0

And start getting following issue.

I'm getting this issue with Lumen 6.0. :( Not sure how to fix it, I don't really want to keep downgrading my Lumen version.

If anybody is looking for an answer. It should be LumenPassport::routes($this->app->router); instead of LumenPassport::routes($this->app); in AuthServiceProvider

\Dusterio\LumenPassport\LumenPassport::routes($app, ['prefix' => 'v1/oauth']);
change to
\Dusterio\LumenPassport\LumenPassport::routes($app->router);
