Hello all, I stumbled upon a weird issue with tagging resources. I am running a stack transformation which tags all of the resources created, like this:

def transformation(args: ResourceTransformationArgs):
    new_props = args.props
    new_props["tags"] = {"blah1": "blah2"}
    return ResourceTransformationResult(props=new_props, opts=args.opts)

pulumi.runtime.stack.register_stack_transformation(transformation)

The issue here is that pulumi throws this error

Diagnostics:
  github:index:RepositoryEnvironment (repo-env):
    error: github:index/repositoryEnvironment:RepositoryEnvironment resource 'repo-env' has a problem: Invalid or unknown key. Examine values at 'repo-env.tags'.

during the creation of a simple GitHub repository environment (code below):

repo_env=github.RepositoryEnvironment(
    resource_name="repo-env",
    environment="dev",
    repository=ams_repo.name,
    can_admins_bypass=True,
)

If I remove the stack transformation, the deployment goes on normally. Any idea on what I am doing wrong? Google is not helping and the less I have to say about Pulumi "AI" the better. Thanks in advance.

Not all resources take tags. What's the usecase?

Had to take a call and din't finish writing. The GitHub repository resource (and most other GitHub resources) does not has any tags. My question is - is there any way to omit them from the stack transformation?

You can conditionally apply your transformation based on the resource type. Take a look at

args.type_

I am auto-tagging azure and github resources in this case

Yes. I'm not aware of any github resources that support

tags

, so you should be able to do

if not args.type_.startswith("github:")

Thank you. Off to the salt mines.
