> Interestingly, this has started to happen in three separate Flink deployments
> at the very same time. The only thing in common between the three deployments
> is that they consume the same Kafka topics.
> No deployments have happened when the issue started happening which was on
> July 28th 3:05PM. We have since been continuously seeing the error.
> We were also able to extract the request that Flink sends to the HTTP
> statefun endpoint:
> {code}{'invocation': {'target': {'namespace': 'com.x.dummy', 'type':
> 'dummy'}, 'invocations': [{'argument': {'typename':
> 'type.googleapis.com/v2_event.Event', 'has_value': True, 'value':
> '-redicated-'}}]}}
> {code}
> As you can see, no `id` field is present in the `invocation.target` object or
> the `target_id` was an empty string.
>
> This is our module.yaml from one of the Flink deployments:
>
> {code}
> version: "3.0"
> module:
> meta:
> type: remote
> spec:
> endpoints:
> - endpoint:
