The tool is RedisInsight

Here is the code:

[iko1]

1. The current implementation of json.get gets two required arguments key and path. I suggest adding the path argument to be an optional argument and in case it's not supplied the code should query the root key.
2. .foo is not valid enhanced path syntax which is explained here: https://goessner.net/articles/JsonPath/ the syntax that you used is called restricted path syntax and it's not supported by the JSON library that the code is using.

@iko1 Thanks for your kind help

1. for redisinsight tool, I find it use 'json.debug memory' command but dragonfly not have, so throw error
2. for jsonpath style, maybe I need change my habits, lol

@romange Hi, I find the reason why redisinsight cant work

1. JSON.SET key path value [NX | XX] current version not support [NX | XX] params
2. JSON.DEBUG MEMORY key [path] current version not support memory params
