celery 4.3, SoftTimeLimitExceeded in group of tasks - celery

Question

How should I handle SoftTImeLimitException with group of celery tasks?
i have task
> #shared_task(bind=True, priority=2, autoretry_for=(EasySNMPError,),
> soft_time_limit=10, retry_kwargs={'max_retries': 3, 'countdown': 2},
> acks_late=True) def discover_interface(self, interface_id: int) -> dict:
> logger.info(f'start disco interface {interface_id}')
> p = probes.DiscoverSNMP()
> try:
> with utils.Timer() as t1:
> p.discover_interface(interface_id=interface_id)
> logger.info(f'stop disco interface {interface_id}')
> except SoftTimeLimitExceeded:
> p.stats['message'] = 'soft time limit exceeded'
> return p.stats
when i run it i get soft time limit exception.

how should i change it to NOT have exception in job.join_native(), but message 'soft time limit exceeded'returned from task?
