It looks like the call to @api_view should be like this:

@api_view(['GET', 'POST'])

In other words, pass in a single list of the permitted HTTP methods. Docs here: https://www.django-rest-framework.org/api-guide/views/#api_view

Other projects with similar function based views was working fine on linux.
