GRPC error when calling DurableClientContext.getClient

Hi,

I'm experimenting with writing a Java Durable function and have been getting this strange error message when I try and kick off an orchestration using DurableClientContext.getClient.

The issue is transient.
I'm using Java 17.
All the durable function packages are up to date.
The error occurs running locally on windows as-well as on an Azure Function app in the cloud (linux).

The weird thing is the orchestrations all seem to run so I'd like to know if this is safe to ignore.

The error message looks like this:
[2024-02-20T07:21:36.332Z] Feb 20, 2024 6:21:36 PM io.grpc.internal.ManagedChannelOrphanWrapper$ManagedChannelReference cleanQueue [2024-02-20T07:21:36.333Z] SEVERE: *~*~*~ Previous channel ManagedChannelImpl{logId=157, target=localhost:4001} was not shutdown properly!!! ~*~*~* [2024-02-20T07:21:36.333Z] Make sure to call shutdown()/shutdownNow() and wait until awaitTermination() returns true.

and it stems from this call where I am about to kick-off a new orchestration.

Is it safe to ignore? Should it be logged out?

Thanks,

Inizia da com.microsoft.durabletask.azurefunctions.DurableClientContext.getClient e traccia come costruisce com.microsoft.durabletask.DurableTaskGrpcClient tramite DurableTaskGrpcClientBuilder. Riproduci localmente l’avviso transitorio di ManagedChannel e confronta il ciclo di vita del client con le indicazioni di gRPC per l’arresto; il lavoro è concluso quando si determina se il canale viene lasciato aperto in modo improprio e se l’avviso debba essere impedito o registrato diversamente.
