[SR-Users] Redis issue when getting results in Kamailio

[Ali Taher via sr-users]

Hello all,

I have redis database where the data is inserted in JSON format:

#Redis Command

JSON.GET Index1J:12345678

#Redis Result
[
  {
    "SupplierID": "7",
    "BCode": "987654",
    "Rate": 0.159
  },
  {
    "SupplierID": "7",
    "BCode": "765432",
    "Rate": 0.159
  },
  {
    "SupplierID": "7",
    "BCode": "5432159",
    "Rate": 0.159
  }
]

When I try to get the result using Lua script in Kamailio like the following:
#kamailio command
  if KSR.ndb_redis.redis_cmd("srvN", "JSON.GET pricelistJ:441246890", "ra") then
            KSR.xlog.xinfo("array size: $redis(ra=>size)\n");
            KSR.xlog.xinfo("Redis Response: " .. tostring(ra) .. "\n")
            KSR.xlog.xinfo("first values: $redis(ra=>value[0]) , 
$redis(ra=>value[1])\n");
        end

Nov 7 07:58:15 868d08ee318d /usr/sbin/kamailio[72]: INFO: LUA {INVITE}: 
<script>: array size: <null>
Nov  7 07:58:15 868d08ee318d /usr/sbin/kamailio[72]: INFO: LUA {INVITE}: 
<script>: Redis Response: nil
Nov  7 07:58:15 868d08ee318d /usr/sbin/kamailio[72]: INFO: LUA {INVITE}: 
<script>: first values: <null> , <null>

I'm getting null results.

I don't know what I'm doing wrong here. Can you please assist?
