route not found on Laravel 5.5

[robertmindroi]

I am trying to use this package in an app, but every time I add it my POST route gives not found exception NotFoundHttpException when used with a JSON payload.

Route::post('/talk', 'ConversationController@talk')->name('talk');

The error is the following

If I remove the package everything is working fine. I am using Laravel 5.5.32

Do you have any insight into this?
