      Version-Release number of selected component (if applicable):

          

      How reproducible:

          Enable networking obfuscation for the Insights Operator and wait for gathering to happen in the operator. You will see the above stacktrace. 

      Steps to Reproduce:

          1. Create a HyperShift hosted cluster with OVN
          2. Enable networking obfuscation for the Insights Operator
          3. Wait for data gathering to happen in the operator
          

      Actual results:

          operator panics

      Expected results:

          there's no panic
