I am fetching some data from server using ajax on page loading. But these calls always returns error as The POST method is not supported for this route. Supported methods: OPTIONS. I have tried all the options I can but no use. Here is my code.

        var today = new Date();
        var monthYear = moment(today).format('MMM/YYYY');
        $.ajax({
            headers: {
                'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
            },
            url: baseUrl + 'statisticalboxes',
            method: 'POST',
            data: {
                'project-month': monthYear
            },
            success: function(data) { 
                console.log(data);
            },
            error:function(e) {
                console.log(e);
            }
        });

web.php

Route::post('statisticalboxes', ['as' => 'statisticalboxes','uses' => 'DashboardController@getStasticalBoxData']);

I have changed method into all other options, but no use. When I look into the network tab, the requested url look like Request URL: http://127.0.0.1:8000/nullstatisticalboxes, but the actual one is Request URL: http://127.0.0.1:8000/statisticalboxes
