fix: Condition observations not relayed when durableRelay is enabled

[Pranay265]

When durableRelay: true, the Condition category observations were not getting relayed. the durable condition code path passes raw IObservationOutput objects directly to MTConnectMqttEntityServer.CreateMessage, which requires observations.DataItem.Device to be set. These raw outputs have Device == null , so CreateMessage() returns null → throws → silently swallowed.

Hi @PatrickRitchie

Just following up on this PR. The issue fixed here is critical for our application, and we would greatly appreciate a review when possible. Please let me know if there are any concerns or changes required from our side.

Thanks!

Sorry for the delay in reviewing. There were some changes made to that same method that I needed to pull in first.

I did change the .Select(o => ...) LINQ statement to use the CloneAsObservation() method that was added in a previous commit. This should perform the same way and will make the code easier to maintain.

Thanks for creating a PR and please feel free to create others!

Thanks for the update and for reviewing the PR.

Could you let us know when the next release is expected? We need to update our application once a version containing this change is available.
