ProductFeesApiModel issue

[x64code]

Looks like there is an issue with the fees API

seems like this might be an issue with the generated code (that we should file on https://github.com/amzn/selling-partner-api-models) since you'd think it'd require the necessary parameters in the method signature, but what params did you pass it?

This still seems to be an issue.
