Cannot start a pipeline with a Notification data sink about streampipes HOT 4 CLOSED

Hi @michaelreisvoid,

thanks for opening the issue.

I attempted to reproduce the problem on a new instance of StreamPipes version 0.95.0. I created a machine data simulator adapter and a Notifications sink, and the pipeline started and worked as expected.

Could you clarify your setup? Did you set up a new StreamPipes instance, or did you migrate from version 0.93.0 to 0.95.0? If you migrated, did you update all of the Docker services or only the backend?
Were there any error logs during the migration process?

Hi @tenthe ,
thanks for the followup

I am using the release directly, running locally with docker compose:
cd ~/apache-streampipes-0.95.0/installer/compose
docker compose up
so everything should be up to date. I just ran a docker system prune -a to be extra sure, and the error still occurs.

I was using the mqtt adaptor, but I just tried with the machine data simulator, and still run into the same issue.

I can create the pipeline, Enable live preview works, the exception just happens when trying to start the pipeline. A colleague of mine also has the same issue.
We just connect an adaptor to a Notification, and this happens every time.

Ok, I also pruned all of my volumes, repeated the steps, and now it works as expected.
Personally this now becomes a non-issue, but it seems there is some sort of a consistency problem when using the same volumes from one version to the next

@michaelreisvoid, ok. Thanks for the information, also if you have any further questions please feel free to ask.

If anyone else is facing this issue during the update from 0.93.0 to 0.95.0, please feel free to reopen this issue.
