[dwalters]

Better handles cases where the YAML is not valid JSON, such as
maps with integer keys (#3446).

Hi @dwalters. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

/ok-to-test

[dwalters]

Looks like YAMLToJSONStrict prohibits duplicate keys, though the error message is slightly different, assume that's OK.

Also removed the special case for lists that was added in 802d79a, since k8syaml handles that as well. The test from that commit passes.

@natasha41575 any update on this one? #3446 is hitting us as well.

[dwalters]

As far as I know this is good to go, happy to address any concerns..
