TincyMCE image upload to server with Laravel

Hello guys,

I'm tyring to upload images with TincyMCE cloud API version. So far submitting textarea with plain text works, but I'm stuck at adding images. I want to upload images to server storage, return URL link and save it in textarea with TinyMCE. I made a route that saves image and returns json with image path, but I get 500 TokenMismatchException in console, before it even hits the end point. I see the image in TincyMCE editor, but i also get red alert: Failed to upload image: HTTP Error: 500. Do i need to somehow add X-CSRF token when sending to the controller?

HTML code:

 <form method="POST" action="/news" enctype="multipart/form-data">
     {{ csrf_field() }}              
      <!--  Form Input  -->
            <textarea class="form-control" name="body" id="body" rows="8">
                 {{ old('body') }}
            </textarea>          
</form>

Here is the tinymce script:

<script>
        tinymce.init({
            selector: 'textarea',
            height: 500,
            setup: function (editor) {
                editor.on('init change', function () {
                    editor.save();
                });
            },
            plugins: [
                "advlist autolink lists link image charmap print preview anchor",
                "searchreplace visualblocks code fullscreen",
                "insertdatetime media table contextmenu paste imagetools"
            ],
            toolbar: "insertfile undo redo | styleselect | bold italic | alignleft aligncenter alignright alignjustify | bullist numlist outdent indent | link image",
            content_css: [
                '//fonts.googleapis.com/css?family=Lato:300,300i,400,400i',
                '//www.tinymce.com/css/codepen.min.css'
            ],
            image_title: true,
            automatic_uploads: true,
            images_upload_url: '/upload',
            file_picker_types: 'image',
            file_picker_callback: function(cb, value, meta) {
                var input = document.createElement('input');
                input.setAttribute('type', 'file');
                input.setAttribute('accept', 'image/*');
                input.onchange = function() {
                    var file = this.files[0];

                    var reader = new FileReader();
                    reader.readAsDataURL(file);
                    reader.onload = function () {
                        var id = 'blobid' + (new Date()).getTime();
                        var blobCache =  tinymce.activeEditor.editorUpload.blobCache;
                        var base64 = reader.result.split(',')[1];
                        var blobInfo = blobCache.create(id, file, base64);
                        blobCache.add(blobInfo);
                        cb(blobInfo.blobUri(), { title: file.name });
                    };
                };
                input.click();
            }
        });
    </script>

and the controller method, that is called on /upload ->

public function store()
    {
        $imgpath = request()->file('name')->store('uploads', 'public');
        return json_encode(['location' => $imgpath]);
    }

If i try to just save image in blob version straight to the database it works, but i think that using storage and URL would be better for performance.

Any help would be very appreciated.
