wireguard kernel module not loaded

[miramo]

Description
Hello, I managed to install the spk (whether already compiled or compiled by myself on the machine), but the problem is that the kernel module does not seem to want to load and I do not know where the problem comes from.

Steps to reproduce

$ sudo /var/packages/WireGuard/scripts/start-stop-status start
net.ipv4.ip_forward = 1
Loaded 7 iptables core modules
Loaded 9 iptables NAT modules
insmod: ERROR: could not load module /wireguard/wireguard.ko: No such file or directory

So, I tried to do :

$ sudo /sbin/insmod /volume1/@appstore/WireGuard/wireguard/wireguard.ko
insmod: ERROR: could not insert module /volume1/@appstore/WireGuard/wireguard/wireguard.ko: Invalid module format

$ lsmod | grep wireguard

Plus, the package seems to be running, but on the interface it is not.

$ sudo synoservice --status pkgctl-WireGuard
Service [pkgctl-WireGuard] status=[enable]
required upstart job:
	[pkgctl-WireGuard] is start.
