Issue with task submission

When I run the sample `cmd/main.go`, which basically does nothing, I get the logs on the container output as:
```

Yes, the task has been submitted. But when I submit a new task, no more logs appear. Any Idea why this is happening? I submit the task using `devkit avs call`

Inizia da cmd/main.go, dove l’esempio registra “Validating task,”, e riproduci il comportamento usando devkit avs call: confronta il primo invio con uno successivo. Segui il percorso di invio dell’attività da quel punto di ingresso e verifica che gli invii ripetuti producano i log previsti oppure segnalino un errore chiaro.
