php - Error Message "GET method is not supported for this route. Supported methods: POST"

When I was click submit button I got an error message .

The GET method is not supported for this route. Supported methods: POST

I have try this method, but still error.

php artisan route:clear
php artisan view:clear

This my code

<form action="{{ route('pemesanan.process') }}" method="post">
  {{ csrf_field() }}
  ...
  ...
</form>

For route

Route::post('pemesanan/process', ['as' => 'pemesanan.process', 'uses' => 'PemesananController@process'])->middleware('auth');

Solution:

your route name is "pemesanan.calculate" but you are using "pemesanan.process" in your form

change your form to solve your problem
