Running any Command in 1.20.4 crashes the server

[ApplecakeYT]

When updated from 1.19.4 -> 1.20.4, tested with a single command readycheck.json containing...

{
	"schemaVersion": 1,
	"commandMode": "COMMAND_CUSTOM",
	"command": "readycheck",
	"permission": 1,
    "actions": [
        {
            "command": "function server:actions/readycheck/init",
            "commandType": "CLIENT"

        }
       ]
}

Crashed the server, here is the crash report [redacted some bits]
