Hi @bradkwadsworth-mw, thanks for the PR.

For failed CI pipelines, please run make submodules and force push the changes.

[bradkwadsworth-mw]

I ran make submodules and there were no changes.

[bradkwadsworth-mw]

@turkenf Any ideas on how I should proceed?

[bradkwadsworth-mw]

@turkenf It looks like the tests are passing now.

[bradkwadsworth-mw]

@turkenf Just rebased against current main.

[turkenf]

/test-examples="examples/cloudplatform/v1beta1/serviceaccount.yaml"

[turkenf]

Thank you for your effort @bradkwadsworth-mw, I left two comments. And, do you have a specific reason for updating the build submodule, if not would you revert it to the same commit as main?

[bradkwadsworth-mw]

@turkenf I think I fixed the issues.

[turkenf]

@bradkwadsworth-mw, as I mentioned here: do you have a specific reason for updating the build submodule, if not would you revert it to the same commit as main?

[turkenf]

And please squash your commits for a clean commit history.

[bradkwadsworth-mw]

@turkenf ok should be good I hope.

[turkenf]

Please add the following lines to PrivateClusterConfigInitParameters and PrivateClusterConfigParameters in the apis/container/v1beta1/zz_cluster_types.go file.

	// +crossplane:generate:reference:type=github.com/upbound/provider-gcp/apis/compute/v1beta2.Subnetwork
	// +crossplane:generate:reference:extractor=github.com/upbound/provider-gcp/config/common.SelfLinkExtractor()

You just need to copy changes in types go file from v1beta2 to v1beta1

[bradkwadsworth-mw]

@turkenf hopefully that should do it.

[turkenf]

Could you please run make generate again and push the changes?

[turkenf]

Thank you @bradkwadsworth-mw, LGTM.
