Parse JSON on Zephyr

Question

Hello
I try to parse json but I've a problem with multiple object :

---

#include <zephyr/data/json.h>

---

struct elt
{
const char *a;
const char *c[16]; // pointeur vers un tableau de chaînes de caractères
size_t num_c; // nombre d'éléments dans le tableau c
};
struct obj_array
{
struct elt elements[10];
size_t num_elements;
};
static const struct json_obj_descr elt_descr[] = {
JSON_OBJ_DESCR_PRIM(struct elt, a, JSON_TOK_STRING),
JSON_OBJ_DESCR_ARRAY(struct elt, c, 16, num_c, JSON_TOK_STRING),
};
static const struct json_obj_descr obj_array_descr[] = {
JSON_OBJ_DESCR_OBJ_ARRAY(struct obj_array, elements, 10, num_elements,
elt_descr, ARRAY_SIZE(elt_descr)),
};
void main(void)
{
int ret;
struct obj_array obj_array_array_ts;
printk("parse : \n");
char encoded[] = "[{\"a\":\"ok\",\"c\":[\"text1\",\"text2\",\"text3\"]}]";
printk("%s\n", encoded);
k_sleep(K_MSEC(1000));
ret = json_arr_parse(encoded, sizeof(encoded),
obj_array_descr,
&obj_array_array_ts);
printk("r : %d\n", ret);
if (ret)
{
printk("error parsing");
}
else
{
for (size_t i = 0; i < obj_array_array_ts.num_elements; i++)
{
printk("a: %s\n", obj_array_array_ts.elements[i].a);
for (size_t j = 0; j < obj_array_array_ts.elements[i].num_c; j++)
{
printk("c %d: %s\n", j, obj_array_array_ts.elements[i].c[j]);
}
}
}
}

With char encoded[] = "[{\"a\":\"ok\",\"c\":[\"text1\",\"text2\",\"text3\"]}]";

This is ok :
parse :

[{"a":"ok","c":["text1","text2","text3"]}]

r : 0

a: ok

c 0: text1

c 1: text2

c 2: text3

With char encoded[] = "[{\"a\":\"ok\",\"c\":[\"text1\",\"text2\",\"text3\"]},{\"a\":\"ok\",\"c\":[\"text1\",\"text2\",\"text3\"]}]";
This is as if it cant see the second object

parse :

[{"a":"ok","c":["text1","text2","text3"]},{"a":"ok","c":["text1","text2","text3"]}]

r : 0

a: ok

c 0: text1

c 1: text2

c 2: text3

c 3:

Have an idea?

Thanks !
