Type must be one of

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.

Solutions

  1. Set the rule type to one of the listed valid types.
  2. Check the VALID_TYPES list in server/endpoints/modelRouter.js.
Defensive patterns

Strategy: validation

When it happens
