cJSON_print() issue

[Shekhar Suthar]

I'm using nRF9160DK and in that cJSON formation give me some error because of that my device will restart again and again

as in code if I'm input cJSON_AddNumberToObject(Data,"Humidity",22); that time its happening but I thing the problem with cJSON_print()

cJSON_AddItemToObject(Device_data1, "data", Data = cJSON_CreateObject());
cJSON_AddStringToObject(Data,"Temperature","67");
cJSON_AddStringToObject(Data,"Humidity","44");
//cJSON_AddNumberToObject(Data,"Humidity",22);

Attribute_json_Data = cJSON_Print(Attribute_json);

????

I had a similar issue and what I found out was that it was related to a wrong behavior in my code: 

In one case I allocated memory using k_malloc but released it with free instead of k_free.

Once I fixed this wrong behavior the crashes disappeared.

So I am still getting crashes after calling cJSON_Init(). My prj.conf is below. I'm at a loss.

CONFIG_CJSON_LIB=y

# newlibc
CONFIG_NEWLIB_LIBC=y
CONFIG_NEWLIB_LIBC_FLOAT_PRINTF=y
CONFIG_FPU=y
CONFIG_FPU_SHARING=y

# Heap and stacks
CONFIG_HEAP_MEM_POOL_SIZE=32768
CONFIG_MAIN_STACK_SIZE=1280
CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=2048
CONFIG_HW_STACK_PROTECTION=y

I fixed this issue by altering my prj.conf file. The main culprit is shown below.

CONFIG_MAIN_STACK_SIZE=4096
