Bottlenose ItemLookup generates HTTP response code 410 Gone Error

Question

I have a Python 3.8 unit test that used to work fine, and now it is failing. I can't see any documentation that says that the method has been deprecated, and so I'm wondering what's going on here.

The unit tests do this:

1. Make sure we instantiated the Bottlenose client
2. Go and look up some product

    def test_amazon_client(self):
        """
        Test that amazon client is created.
        """
        self.assertIsNotNone(self.amazon)

    def test_asin(self):
        """
        Test that amazon client is pulling product data.
        """
        result = self.amazon.ItemLookup(ItemId="B000Q5Z8L0")
        self.assertIsNotNone(result)

When the unit test runs, the output shows a "HTTP 410: Gone" error.

ERROR: test_asin (__main__.TestAmazon)

    return urllib2.urlopen(api_request, timeout=self.Timeout)

    return opener.open(url, data, timeout)

    response = meth(req, response)

    response = self.parent.error(

    return self._call_chain(*args)
  File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/urllib/request.py", line 502, in _call_chain
    result = func(*args)

    raise HTTPError(req.full_url, code, msg, hdrs, fp)
urllib.error.HTTPError: HTTP Error 410: Gone

So this leaves me scratching my head.

1. I made sure I was on up to date boto3 client.
2. I made sure the item being looked up was valid.
3. I made sure the client was being instantiated.

Any other pointers would be helpful.
