Selecting the current workspace blows up

[kalbasit]

I am currently on the current workspace, identified by the number 1, I am using the following script

package main

import "github.com/proxypoke/i3ipc"

func main() {
        i3ipc, err := i3ipc.GetIPCSocket()

        if err != nil {
                panic(err)
        }

        i3ipc.Command("workspace 1")
}

When I run it (to selected the currently selected workspace), it crashes with the following error:

$ go run i3_ipc.go
panic: runtime error: index out of range

goroutine 1 [running]:

@eMxyzptlk: In case you are still interested in this you might want to give my primitive fix a shot.

This is not a bug in i3ipc, but in i3: i3/i3#2565
It looks like this is currently getting fixed, so no need to implement workaround here ;)
