dm_init(&init_data) returns invalid parameter

[c cook]

I'm using SDK 7.1, PCA10028 eval board, SD310 2.0.1, MCP 3.6.0.8331

I'm trying to implement bonding. I first initialize pstorage, as a separate call from main. Then I call sec_params_init();

static void sec_params_init(void)
{
    uint32_t										err_code;
		dm_application_param_t 			register_param;
		dm_init_param_t        			init_data;
	
	  err_code = dm_init(&init_data);
    APP_ERROR_CHECK(err_code);
	
		memset(&register_param.sec_param, 0, sizeof(ble_gap_sec_params_t));
    
    register_param.sec_param.timeout      = SEC_PARAM_TIMEOUT;
    register_param.sec_param.bond         = SEC_PARAM_BOND;
    register_param.sec_param.mitm         = SEC_PARAM_MITM;
    register_param.sec_param.io_caps      = SEC_PARAM_IO_CAPABILITIES;
    register_param.sec_param.oob          = SEC_PARAM_OOB;
    register_param.sec_param.min_key_size = SEC_PARAM_MIN_KEY_SIZE;
    register_param.sec_param.max_key_size = SEC_PARAM_MAX_KEY_SIZE;
    register_param.evt_handler            = device_manager_evt_handler;
    register_param.service_type           = DM_PROTOCOL_CNTXT_GATT_SRVR_ID;

    err_code = dm_register(&m_app_handle, &register_param);
    APP_ERROR_CHECK(err_code);

The call err_code = dm_init(&init_data); returns a value of 0x0007 (Invalid parameter); What's wrong?

Thanks

The error was in pstorage_init. I was not setting up cmd_queue
