--headful params

[waitingSunset]

i use
swarm --headful -f locustfile.py --loadgen-list 10.20.254.1,10.20.254.2--processes -1

[swarm.py:545] launching master: locust --master --master-bind-port 5557 --master-bind-host=127.0.0.1 --expect-workers -2 --expect-workers-max-wait 60 --headless -f locustfile.py --exit-code-on-error 0 --headful

[swarm.py:400] workers started ssh -q -R 5557:localhost:5557 -R 5558:localhost:5558 10.20.254.1' PYTHONUNBUFFERED=1 locust --worker --processes -1 --master-port 5557 --headless --expect-workers-max-wait 30 -f - & read; kill -9 $! '
result:
/ERROR/locust.main: Invalid --expect-workers argument (-2), must be a positive number

i think --headful with --processes -1 not replace --headless
