Advertising data update NRF_ERROR_INVALID_ADDR

Question

I'm trying to use the new ble_advertising_advdata_update from SDK 15.1 by doing 
 ble_gap_adv_data_t adv_data;
uint8_t data[2];
memcpy(&data, &m_adv_manuf_array, sizeof(m_adv_manuf_array));
adv_data.adv_data.p_data = data;
adv_data.adv_data.len = sizeof(data);
ret_code = ble_advertising_advdata_update(&m_advertising, &adv_data, true);
APP_ERROR_CHECK(ret_code); 
 but I get NRF_ERROR_INVALID_ADDR 
 What do I need to do to get it to work?

I solved it like this. I had hoped that there would be some simpler way to update the manufacturer specific data while advertising. 
 void advertising_update()
{
 ret_code_t ret_code;

 static bool buffer_index; // We alternate between two data buffer in order to hot-swap
 static ble_gap_adv_data_t new_data;
 ble_gap_adv_data_t *old_data = &m_advertising.adv_data;

 // Copy advertising data
 static uint8_t data[2][BLE_GAP_ADV_SET_DATA_SIZE_MAX];
 new_data.adv_data.p_data = data[buffer_index];
 new_data.adv_data.len = old_data->adv_data.len;
 memcpy(new_data.adv_data.p_data, old_data->adv_data.p_data, old_data->adv_data.len);

 // Update manufacturer specific data
 const uint8_t manuf_data_offset = 15;
 adv_manuf_data_update();
 memcpy(&new_data.adv_data.p_data[manuf_data_offset],
 &adv.manuf_data_array,
 sizeof(adv.manuf_data_array));

 // Copy scan response data
 static uint8_t scan_data[2][BLE_GAP_ADV_SET_DATA_SIZE_MAX];
 new_data.scan_rsp_data.p_data = scan_data[buffer_index];
 new_data.scan_rsp_data.len = old_data->scan_rsp_data.len;
 memcpy(new_data.scan_rsp_data.p_data,
 old_data->scan_rsp_data.p_data,
 old_data->scan_rsp_data.len);

 ret_code = ble_advertising_advdata_update(&m_advertising, &new_data, true);
 APP_ERROR_CHECK(ret_code);

 buffer_index = !buffer_index;
}

Advertising data update NRF_ERROR_INVALID_ADDR
