Like get cache key, plus JSON: when the stored string parses as JSON, the decoded value is also emitted on the block's dynamically-typed output pin (the selected field type). Invalid JSON is NOT an error : the typed output simply stays unset while value keeps the raw string. Fails with INVALID_TYPE when no field type is selected on the block and with MISSING_REDIS_KEY when no key is configured.
redis get |
A typical wiring for get cache json key: a function trigger starts the flow; the flow out pin feeds debug.
