My Pulumi automation program has started throwing exceptions (via the dotnet-sdk) when I call stack.UpAsync(). The exception message includes "stderr: warning: A new version of Pulumi is available. To upgrade from version '3.5.1' to '3.6.0'". Is the Pulumi sdk really throwing an exception to force me to upgrade?

it shouldn't be throwing an exception, just a warning. in any case, you can disable this check by setting the environment variable

PULUMI_SKIP_UPDATE_CHECK=true

@billowy-army-68599 Is there an api I can call to set the same environmental value? I ask because I will be running my Pulumi automation program in a transient container runtime, this is currently a pub-sub subscriber within a Dapr application.

@icy-football-94152 there's no API no, but you could set the env var at the container level (assuming it's a Docker container)

ENV PULUMI_SKIP_UPDATE_CHECK=true
