Blobmsg_parse hangs

For Developers
1

Hello Team,
I have been facing an issue with ubus cli call hangs when I sent an integer type parameter to my custom rpcd plugin expecting a string. but when I send the proper string type, it works. I think this should be handled properly in ubus.
Below is my UBUS method

UBUS_METHOD("setNotification", rpc_set_notification, rpc_set_notification_policy),

and below is my policy

const struct blobmsg_policy 
rpc_set_notification_policy[RPC_NOTIFICATION_ARG_MAX] = {
	UBUS_BLOB_POLICY_STRING("id")
};

and below call hangs and return timeout error

ubus call object setNotification '{"id": 1}'

Thanks,
gargsa

/ # ubus call object setNotification '{"id":1}'
Command failed: Request timed out

The above error that I am getting

and the below works

/ # ubus call object setNotification '{"id":"softwareUpdate"}'
{
        "result": 0
}
