Hello, I have a TS pulumi program that is using a dynamic nodejs provider defined within the project. We are seeing a strange issue in our CI system (Gitlab) only. This one's a bit of a headscratcher because I cannot reproduce it outside of CI. It runs preview/up just fine on my local dev env and in my local docker instance (we use the same image in CI) -- however in CI we see this (See thread)

I wonder if those two stdout/stderr errors are relevant? Maybe the GitLab-CI docker env has permissions set on those that the app isn't prepared for? The --non-interactive code changes a few then when outputting to consoles; maybe try without that flag and see if the regular code handles things better?
It should automatically detect that stdout/stderr can't handle colours; I don't know what else the flag does.

Hi @little-cartoon-10569 thanks for the suggestions. Changing the non-interactive flag didn't do anything. However, we think there's an issue with the grpc-js and usage of *_PROXY vars. When we unset all our proxy variables the pipeline started running. We haven't pinpointed the exact issue yet but this was a big revelation.
Another fun fact, not sure if it's documented anywhere, but using both
--verbose=
flag with
--debug
seems to cancel the
--debug
output
It was indeed the corporate proxy vars. grpc-js v0.7.0 and above introduce proxy handling and their
no_proxy
configuration only accepts a comma separeted list of host names. regular no_proxy conventions allow CIDR ranges and hostname prefixes. in our case we had
127.0.0.0/8
in no_proxy but it was not respected by the grpc library. so it was trying to send
127.0.0.1
traffic over the corp proxy.
