Trying to recreate inline python gcp example from https://github.com/pulumi/automation-api-examples/blob/main/python/inline_program/main.py . All seems to work well (=resources get created in GCP) till the execution of this line:

up_res = stack.up(on_output=print)

. It outputs:

E0819 14:48:02.366739000 4372022656 <http://fork_posix.cc:76]|fork_posix.cc:76]>                  Other threads are currently calling into gRPC, skipping fork() handlers

Any ideas what's going on here? Running on zsh/mac m1.
