Question: Check if table value exist and contains content

[tiCeR 0]

I try to read a json value but it is not always present in the response.

 

The Problem is that it always ends in : [ERROR] 20:13:07: line getSelfId();..."]:16

 

Is there another solution for the way to check the response code?

 

Thanks for your help! I try to learn fast to give something back

-- I need to know here if result[1] contains playerid

-- empty request would look like: {"id":1,"jsonrpc":"2.0","result":[]}
-- Positive request looks like: {"id":1,"jsonrpc":"2.0","result":[{"playerid":0,"type":"audio"}]} or {"id":1,"jsonrpc":"2.0","result":[{"playerid":1,"type":"video"}]}
if resp_decode.result[1].playerid then
local playerid = resp_decode.result[1].playerid;
