API plugin isn't working with the file upload

Describe the bug

So Im adding the documentation of the api with paloalto plugin.
And in this documentation, we added options and one of this is to add a file uploaded.
When I see the code with the curl widget is ok and working fine. But when I use the python formatted code, I don't see the file uploaded.

Expected behavior

To see the file uploaded in the right argument of the python code.

Current behavior

So when you have the plugin api installed in the documentation you can see the the parameters being filled according to the options.

Steps to reproduce

Start by reproducing the issue in the API documentation with the Palo Alto plugin and compare the generated curl and Python examples for a file-upload parameter. Done means the generated Python code includes the uploaded file in the correct argument, matching the curl example.
