Re: [milo-dev] Exception swallowed when subscription transfer fails

[Kevin Herron <kevinherron@xxxxxxxxx>]

Jose,

Based on those logs I would expect onSubscriptionTransferFailed to be invoked 3 times, one for each of the subscriptions that failed to transfer and received a Bad_SubscriptionIdInvalid operation result.

The code path being followed based on the logs is here: https://github.com/eclipse/milo/blob/b2c089e7124e5d91e726292af573a324bff3102c/opc-ua-sdk/sdk-client/src/main/java/org/eclipse/milo/opcua/sdk/client/session/SessionFsmFactory.java#L965-L1006

If you are not seeing these calls happen then perhaps you do not actually have a listener registered at the time these log statements occur.

Hi all!

We are testing our server capabilities using an OPC that restars itself every hour. Because of that we are expecting the event 'onSubscriptionTransferFailed' to happen, but we see the below instead:

DEBUG: TransferSubscriptions supported: StatusCode{name=Good, value=0x00000000, quality=good}
DEBUG: TransferSubscriptions results: [id=1845337829/Bad_SubscriptionIdInvalid, id=1845337828/Bad_SubscriptionIdInvalid, id=1845337830/Bad_SubscriptionIdInvalid]
DEBUG: TransferSubscriptions succeeded

Is it possible to have that 'Bad_SubscriptionIdInvalid' (or others) not being swallowed and throwing 'onSubscriptionTransferFailed'?

Log attached.

Regards.
