Skaffold YAML reference page broken

[briandealwis]

The skaffold.yaml reference page is broken. It appears to be related to the update of lit-html in #3466

The code is breaking at line 110:

skaffold/docs/content/en/docs/references/yaml/main.js

Lines 114 to 116 in 650ed4b

	} else if ((definition.type === 'array') && value && (value !== '[]')) {
	// Parse value to json array
	const values = JSON.parse(value);

value is "." from the default value of the KustomizeDeploy's paths property, which is defined as an array of strings.

skaffold/docs/content/en/schemas/v2alpha3.json

Lines 1602 to 1610 in 650ed4b

	"paths": {
	"items": {
	"type": "string"
	},
	"type": "array",
	"description": "path to Kustomization files.",
	"x-intellij-html-description": "path to Kustomization files.",
	"default": "."
	}

And sure enough, "." isn't an array of strings.

But this default hasn't changed in ages, so it must be the lit-html. What's puzzling is why this error didn't show up during testing of #3466?

Thank you for the analysis, @briandealwis! There was a kustomize change (#3585) that went in after the lit-html change that changed the type of kustomize paths to array of strings from string. I believe the issue is with the default value setting there.
