Invalid file Uploading a video using Spatie Medialibrary and Dropzone

Please I want to add a feature for Video upload using Spatie Medialibrary but I keep getting this error.

{
  "message": "The given data was invalid.",
  "errors": {
    "file": [
      "The file failed to upload."
    ]
  }
}

While the error message sounds simple to understand I have tried to figure out the problem for over 48 hours. Does it mean that Spatie Medialibrary can't be used for video upload? Below is what I have tried

<!-- Video Field -->
<div class="form-group align-items-start d-flex flex-column flex-md-row">
    {!! Form::label('video', trans("lang.e_service_video"), ['class' => 'col-md-3 control-label text-md-right mx-1']) !!}
    <div class="col-md-9">
        <div style="width: 100%" class="dropzone video" id="video" data-field="video">
        </div>
        <a href="#loadMediaModal" data-dropzone="video" data-toggle="modal" data-target="#mediaModal" class="btn btn-outline-{{setting('theme_color','primary')}} btn-sm float-right mt-1">{{ trans('lang.media_select')}}</a>
        <div class="form-text text-muted w-50">
            {{ trans("lang.e_service_video_help") }}
        </div>
    </div>
</div>

Below is my Controller code

public function store(CreateEServiceRequest $request)
{
    $input = $request->all();
    
    try {
        $eService = $this->eServiceRepository->create($input);

        if (isset($input['video']) && $input['video']) {
            $fileUuid = $input['video'];
            $cacheUpload = $this->uploadRepository->getByUuid($fileUuid);
            $mediaItem = $cacheUpload->getMedia('video')->first();
            $mediaItem->copy($eService, 'video');
        }
    } catch (ValidatorException $e) {
        Flash::error($e->getMessage());
    }

    Flash::success(__('lang.saved_successfully', ['operator' => __('lang.e_service')]));

    return redirect(route('eServices.index'));
}

Please any assistance will be appreciated. Thank you!

After couple of researches. I figured out that all my codes were correct but i needed to declare a strict rules that would contain all the file formats I wanted to accept through the Dropzone. So I had to declare the below array of file formats to test stuffs out

    return [
        'file' => 'mimes:jpeg,png,jpg,gif,svg,pdf,doc,docx,xls,xlsx,ppt,pptx,mp4',
    ];

Also I learnt that the maxFilesize: 500, of the Dropzone is in bytes. So I had to increase it to equivalent of 10MB.

When my code went live, I had a timeout errors trying to upload files of 8MB. So, I also learned that the Dropzone has a timeout property timeout: 9000, /*milliseconds*/, which I set to 0. Which mean no limit.

I hope this helps someone out there. Thanks to everyone!
