Environment

Python version: 3.6.9
NetBox version: 2.9.3

Steps to Reproduce

  1. Create custom field called "bugreport" of type Selection with options apple, orange, banana
  2. Find the IDs of the choices we just made
curl --request GET \
  --url https://netbox.example.com/api/extras/_custom_field_choices/ \
  --header 'accept: application/json' \
  --header 'authorization: Token $token' \
  --header 'content-type: application/json' \

In my case this is: 67,69,68

  1. Create a fresh Prefix to assign an IP in:
curl --request POST \
  --url https://netbox.example.com/api/ipam/prefixes/ \
  --header 'accept: application/json' \
  --header 'authorization: Token $token' \
  --header 'content-type: application/json' \
  --data '{
  "prefix": "10.10.10.0/24"
}'

  1. Make sure the Webhook for the IPAddress object is enabled

  2. Make a request to assign an IP in the above create Prefix, with one of the custom options found above. In this case the Prefix ID is 11913

curl --request POST \
  --url https://netbox.example.com/api/ipam/prefixes/11913/available-ips/ \
  --header 'accept: application/json' \
  --header 'authorization: Token $token' \
  --header 'content-type: application/json' \
  --data '{
  "description": "testserver1",
  "custom_fields": {
    "bugreport": 67
  }
}'

Expected Behavior

IP Address to be assigned with a custom field, of the Selection type, filled out

Observed Behavior

Get the following error

<pre><strong>&lt;class &#x27;AttributeError&#x27;&gt;</strong><br />
Got AttributeError when attempting to get a value for field `value` on serializer `CustomFieldChoiceSerializer`.
The serializer field might be named incorrectly and not match any attribute or key on the `int` instance.
Original exception text was: &#x27;int&#x27; object has no attribute &#x27;pk&#x27;.

Python version: 3.6.9
NetBox version: 2.9.2</pre>

                            If further assistance is required, please post to the <a href="https://groups.google.com/forum/#!forum/netbox-discuss">NetBox mailing list</a>.
                        </p>

</html>

Note that this is a re-open of #5029, and looks to be related to #5081. Based on the advice in #5081, I have tried restarting my netbox-rqworker service but still seem to be getting the same issue. Disabling the IPAddress Webhook is still a work around.

If there is anything else I can provide please let me know
