What happened

I tried to use Enable Product API but it is failing on type error when using multiple methods on instance class of EnabledProductsApi:

    api_response = api_instance.get_enabled_product(**options)

TypeError: EnabledProductResponseLinks._from_openapi_data() got multiple values for argument '_self'

The above error is raised also for python example code from the Fastly documentation.

Please try to reproduce this with version 5.7.0 or later; if it's still an issue we'll try to get it resolved.

Hey @kpfleming, I can confirm this issue still exists.
I looked into it a bit and the problem is the way wrapped_init changes the response json keys into python keys.

The enabled-product APIs return an object with a key named "self". In change_keys_js_to_python "self" is converted to "_self". This makes it so that fn is called with 2 _self arguments.

This is an example response from the API as per the documentation

{
  "product": {
    "id": "product-id",
    "object": "product"
  },
  "service": {
    "id": "4nWURjwmQjbMB5OefSM75i",
    "object": "service"
  },
  "_links": {
    "self": "https://api.fastly.com/enabled-products/v1/product-id/services/4nWURjwmQjbMB5OefSM75i",
    "service": "https://api.fastly.com/service/4nWURjwmQjbMB5OefSM75i"
  }
}

The "self" key in the _"links" object is turned into "_self", which is then forwarded to fn like so when deserializing it into the EnabledProductResponseLinks -

return fn(_self, *args, **kwargs)  # kwargs contains _self='...'

which causes the _self argument to be passed into fn multiple times.

I hope explained the issue clearly 😄

I don't mind opening a PR to fix this.
My first thought was to rename the _self variable to _self_ in order to overcome the name collision. WDYT?

[kpfleming]

Thanks for finding the issue! We can't accept a PR directly against this repo as the code here is produced by a generator (in a private repository), but we can take these details and produce a fix for the generator.

@kpfleming Happy to help!
