            static_configs:
            - targets:
              - ${env:MY_POD_IP}:8888
        target_allocator:

FYI I've opened the issue here, so I can reference it in change log. It is duplicate as in issue opened in Operator, but the issue seems to be on the Collector side ( Prometheus Receiver), see PR -> #36063

Ah, sorry. I missed that it was referencing an issue in another repo.
