Example response

"type": "https://docs.test.konsolutelab.uk/errors/subscription.transition_not_allowed",
"title": "…",
"status": 409,
"code": "subscription.transition_not_allowed",

}Handling it
Branch on code, not on title or the status alone, and log traceId. Codes are stable; new codes may appear, so fall back on the HTTP status for a code you do not know. See Handling errors and the list of codes.
