The problem arises when the json object has two consecutive strings and the first is null. The library is unable to parse the next object value.
I reproduced the problem using the json_app example provided with the simplelink_cc32xx_sdk_4_40_00_07.
This example uses three jsons they are very similar. But only two of them give the right value to the key "lk".
The first is the original json, it has a key named "kp" wich value is null before the key "lk" with value "AB0123456789".
,\"wm\":0,\"kp\":null,\"lk\":\"AB0123456789\", ---> the query "lk" returns null
in the second json The "kp" key has a value and the library is able to retun the value of "lk".
\"wm\":0,\"kp\":\"AB0123456789\",\"lk\":\"AB0123456789\",\"ot\":1}"; the query "lk" returns AB0123456789
The third json is identical to the first one but the order of keys is changed, "kp\":null,\"wm\":0,\"lk\":\"AB0123456789\". So it seems that when the strings are together and the first value is null the seccond value is also asumed null.
\"kp\":null,\"wm\":0,\"lk\":\"AB0123456789\", --->
