Hey folks, I have narrowed down an issue with pulumi preview hanging to the AWS

cloudformation.Stack

module, I am running the following command to bring up pulumi preview:

pulumi up --logtostderr -v=9 --debug 2> /tmp/out.txt

the log file always hangs at the following entry

I0902 10:44:30.806398   96259 eventsink.go:59] adding resolver weighted_routing_policies
I0902 10:44:30.806446   96259 eventsink.go:62] eventSink::Debug(<{%reset%}>adding resolver weighted_routing_policies<{%reset%}>)

here is a copy of my stack
