Swap the commented line setting `c` for expected behaviour.
import celery
app = celery.Celery(broker="redis://", backend="redis://")
@app.task
def nop(*_):
pass
@app.task
def die(*_):
raise RuntimeError
@app.task(bind=True)
def replace(self, with_):
with_ = celery.Signature.from_dict(with_)
raise self.replace(with_)
@app.task
def cb(*args):
print("CALLBACK", *args)
#c = celery.chain(nop.s(), die.s())
c = celery.chain(nop.s(), replace.si(die.s()))
c.link_error(cb.s())
c.apply_async()Expected Behavior
cb should be called as a new-style errback because it accepts starargs
Actual Behavior
cb is not called
