DRF upload extracted zip files

Question

I'm going to upload some files through my DRF API. This API receives a .zip file that has some .xlsx files in. I extract its content in the API view. Then I send this data to the serializer, But I get this error:

[
{
    "file_name": [
        "The submitted data was not a file. Check the encoding type on the form."
    ]
}

]

This is how I'm extracting my .zip file before passing data to the serializer:

def _get_serializer_initial_data(self):
    with ZipFile(self.request.FILES.get('file_name')) as input_zip:
         return [
              {
             'file_name': input_zip.open(_input_excel)
              }
            for _input_excel in input_zip.infolist()
                ]

Then I send data to the serializer this way:

initial_data = self._get_serializer_initial_data()
serializer = self.get_serializer(data=initial_data, many=True)

I checked the extracted files type in the serializer class and it's ZipExtFile, which seems to be unacceptable by DRF. Any help would be appreciated.
