Description

Error in train when implementing file arguments in get_train_args: ERROR aiohttp.server TypeError: Object of type FileField is not JSON serializable

Steps to Reproduce

  1. Download demo_app (or any other use case).
  2. Add a file type into get_train_args: 
    def get_train_args():
arg_dict = {
    "demo-image": fields.Field(
        required=True,
        type="file",
        location="form",
        description="image",
    ),
}
return arg_dict
  3. Run deepaas: deepaas-run ...
  4. Call train method providing a dummy txt or any other file.

Expected behavior:

Get the file as argument on train function (as in predict).

Actual behavior
