[Bug]: easypost.Event.retrieve_all_payloads results in AttributeError: type object 'Payload' has no attribute 'construct_from'

[NathanSmeltzer]

Software Version

7.13.0

Language Version

3.10.8

Operating System

Ubuntu 22.04.2

What happened?

1. I'm trying to retrieve payloads for an event as described in the api docs:

import easypost
easypost.api_key = config("EASYPOST_API_KEY_TEST")
def test_list_payloads():
    # api documentation: https://www.easypost.com/docs/api/python#retrieve-a-list-of-payloads
    payloads = easypost.Event.retrieve_all_payloads(
        "evt_a93cbcd2fbef11ed9b16693a7541b68d"
    )

2. The test fails with this error (line 84 from easypost_objects.py

             cls = getattr(easypost, class_name, EasyPostObject)
`>           obj = cls.construct_from(values=response, api_key=api_key, parent=parent, name=name)
E           AttributeError: type object 'Payload' has no attribute 'construct_from'`

What was expected?

The call did not return a list of payloads as expected.

Sample Code

No response

Thanks for reporting this! It appears that Payload doesn't inherit Resource which then inherits EasyPostObject which has the construct_from function. I've put up #285 which should patch this issue and get you on your way. Should have a release out today.

[Justintime50]

v7.13.1 is released and should fix this bug, let me know if you have further problems with this!

Thank you so much!
