Creating changes seems to fail with a panic when checking metadata or annotations

[illegalnumbers]

What happened?

I ran pulumi preview with a kubernetes cluster backing it and got a panic stack trace exception that appears to be related to metadata or annotations on a resource. This has happened with two different resources, a NamespacePatch and a CustomResourceDefinition. See below for the stack trace.

Example

 panic: fatal: An assertion has failed: path: [metadata annotations]  |  v: <nil>  | old: <nil>  |  oldInput: <nil>

We also tried with the latest 3.x version which received the same problem.

Other things tried - removing ~/.pulumi, removing node_modules and reinstalling, relogging in to gcp where the cluster is located at, etc.

@illegalnumbers could you give a code example of a resource where you've seen this?

yea i can try to get a better repro in a bit, i need to get my stacks fixed first :) but afterward i will work on having something better here

[mjeffryes]

@illegalnumbers did you end up constructing a code example? We can't offer much help without a reproduction.
