Datadog Airflow OAuth Integration not working

[dalsania1]

I am attempting to use the OAuth Reader as part of the airflow datadog integration by following the documentation outlined here.
https://github.com/DataDog/integrations-core/blob/e1dda566ad5aa2c921a396077cb8f0f8c42bba75/airflow/datadog_checks/airflow/data/conf.yaml.example
I am deploying the datadog agent via helm and using the following airflow configuration settings.

datadog:
  confd:
    airflow.yaml: |-
      ad_identifiers:
        - <MY_CONTAINER>
      init_config: {}
      instances:
          url: "https://%%host%%:8443"
          auth_token:
            reader:
              type: oauth
              url: <MY_URL>
              client_id: "%%env_AIRFLOW_CLIENT_ID%%"
              client_secret: "%%env_AIRFLOW_CLIENT_SECRET%%"
              options:
                resource: <MY_RESOURCE>
            writer:
              type: header
              name: Authorization
              value: Bearer <TOKEN>
              placeholder: <TOKEN>

When the datadog agent goes to run the airflow check, I see the following error:

      Traceback (most recent call last):

      TypeError: '>=' not supported between instances of 'float' and 'NoneType

I suspect that the code here is causing the issue:

integrations-core/datadog_checks_base/datadog_checks/base/utils/http.py

Lines 836 to 842 in 74defa8

	self._token = None
	self._expiration = None
	def read(self, **request):
	if self._token is None or get_timestamp() >= self._expiration or 'error' in request:
	global oauth2
	if oauth2 is None:

Is this a bug in the code or am I just not passing in the airflow configuration values correctly?

Thank you
