400
field member: sometimes present
Source: service_error
Emitted by the ValidationError class in lib/authz.ts. lib/docks/service.ts throws it (the ‘No org available to own the dock’ 400); the docks adapters’ field-validation 400s were folded into application/problem+json at C2 too (app/api/docks/route.ts, app/api/docks/[id]/route.ts, via lib/problem.ts’s apiProblemResponse).
