com_read getting failed for billing profile and instantaneous profile

hello,
below code is for to read instantaneous and billing profile - - >

void
read_meter_instantaneous_profile()
{
gxProfileGeneric profile;
char * data = NULL;
cosem_init(&profile.base, DLMS_OBJECT_TYPE_PROFILE_GENERIC, "1.0.94.91.0.255");

com_read(&profile.base, 2);

/* Read rows by entry */
com_readRowsByEntry(&profile, 1, 2);

/* Read rows by Range */
// gxtime start_time;
// gxtime end_time;
// end_time.value = 1742302940; //EPOCH time
// start_time.value = end_time.value - 1 * 60 * 60;
// com_readRowsByRange(&profile, &start_time, &end_time);

obj_toString(&profile.base, &data);
obj_clear(&profile.base);
printk("DEBUG_METER_DATA : Meter Instantaneous Profile --- %s", data);

obj_clearProfileGenericBuffer(&profile.captureObjects);
obj_clearProfileGenericBuffer(&profile.buffer);
free(data);
}

void
read_meter_billing_profile()
{
gxProfileGeneric profile;
char * data = NULL;
cosem_init(&profile.base, DLMS_OBJECT_TYPE_PROFILE_GENERIC, "1.0.98.1.0.255");

com_read(&profile.base, 2);

/* Read rows by entry */

/* Read rows by Range */
// gxtime start_time;

}

we are able to read,

com_read is getting failed , showing Invalid Object on terminal logs,
but when i connect with DLMSDirector, able to read data for billing and instantaneous profile.
