A parameter has a value the endpoint doesn’t accept. A wrongly typed string or number gets parameter_invalid_string or parameter_invalid_integer instead. Examples:
  • a value outside an allowed set
  • an array with too few or too many items
  • the same value repeated within one request where it must be unique, reported in invalid-params
  • a malformed X-Organization-Id header
  • an unknown vehicle ID, or a vehicle with no bank account for payouts

How to fix

invalid-params[].reason explains what is wrong with each value. A vehicle with no bank account for payouts needs Nova support to set one up. After that, send the request with a new Idempotency-Key.
