How to handle NotImplemented responses from chargers

[razvanphp]

For every message that a charger does not implement, like the backported ExtendedTriggerMessages or GetLogs, it responds with:

[
    4,
    "6961263434",
    "NotImplemented",
    "",
    []
  ]

How can we handle this gracefully in the validator?
