Function validateSpecAgainstSchema

cli/cmd/specs.go:142–156

validateSpecAgainstSchema validates spec against a JSON schema string. Mirrors the lenient gRPC-side semantics: an empty or unparseable schema is logged and treated as "skip validation". Used both by validatePluginSpec (after a successful gRPC GetSpecSchema) and by the Hub-API path in validateConfig

(jsonSchema string, spec any)

// (after a successful gRPC GetSpecSchema) and by the Hub-API path in
// validateConfig.
func validateSpecAgainstSchema(jsonSchema string, spec any) error {
	if len(jsonSchema) == 0 {
		// This will also be true for Unimplemented response (schema = nil => schema.GetJsonSchema() = "")
		log.Info().Msg("empty JSON schema for plugin spec, skipping validation")
		return nil
	}

	sc, err := parseJSONSchema(jsonSchema)
	if err != nil {
		log.Err(err).Msg("failed to parse spec schema, skipping validation")
		return nil
	}

	return sc.Validate(spec)
