`failure.unknown_context_field`

Rejected failure has no such field.

Area 4, Failures; not declinable; the next step is usually the agent's.

example

type Lookup = Text {}type Missing = Failure {    kind: FailureKind.not_found    internal: {        lookup: Lookup    }}action find(lookup: Lookup) fails Missing -> Lookup {    reject Missing {        lookup: lookup        search: lookup    }}

jadpo checkcheck failed: 1 error, 1 file

error Missing has no field search

--> main.jadpo:13:9

   |13 |         search: lookup   |         ^^^^^^ not declared

reason: Missing's fields are lookup. A failure carries only the fields its client and internal blocks declare.
next: Remove search, or declare it in Missing's client or internal block (agent)
rule: failure.unknown_context_field
