Hey, I'm having an issue where pulumi overwrites the stack config file on each run (`Pulumi.production.yaml`) it sorts all the keys and removes all comments and whitespace.
Is there some way to prevent it from doing this? I have a bunch of comments and logical grouping/ordering that I don't want to get lost

I've never had Pulumi remove my comments.  Are you using the automation API by chance?

As far as I know, Pulumi stack configuration is tightly-coupled with these YAML files.  To the point that the CLI and Automation API which wraps the CLI require them.

<https://github.com/pulumi/pulumi/blob/master/sdk/nodejs/automation/localWorkspace.ts#L31-L43>

I'm not using the automation api directly, but the file is overwritten/reserialised on each pulumi preview or pulumi up - so I guess something could be going on with that automation api

We'd need to see more code to make a determination.  The stripping on the comments in the Pulumi stack configurations is not something I've ever had happen.

It seems I'm running into specifically this: <https://github.com/pulumi/pulumi/issues/6848|https://github.com/pulumi/pulumi/issues/6848>
Which would be addressed by this age old issue: <https://github.com/pulumi/pulumi/issues/423|https://github.com/pulumi/pulumi/issues/423>
