Token passes the Service Task without execution

I’ve got a simple diagram with a Service Task in the middle - with External as implementation.
When a new process instance is created - it just passes through the External task and ends the process:

I’ve also tried not to subscribe to the topic to see if the token will be stuck on the external task - it also passed.
What may be the reason for such behaviour?

can you upload your model?

Hi @Ivan_Shvets,

either your deployed process model uses a delegate class as service execution or there is another worker running on the network.

You can inspect the external task log with a rest call: or use the history of the cockpit if you have the enterprise edition installed.

Hope this helps, Ingo
