in your routes/api.php file there is a default route comment it or remove it and run the command again.

you are getting the error because of

Route::middleware('auth:api')->get('/user', function (Request $request) {
    return $request->user();
});

move that closure functionality to some controller and access it. something like:

Route::middleware('auth:api')->get('/user', 'UserController@user');
