Type must be one of: ${VALID_TYPES.join(", ")}

Error message

Type must be one of: ${VALID_TYPES.join(", ")}

What it means

Validation error propagated from ModelRouterRule.create: the rule's type field is not one of the enumerated VALID_TYPES, so the router cannot interpret the rule and creation is refused with the allowed list.
