> gokart version
v0.5.1
> go version
go version go1.21.5 darwin/arm64

The go program that reproduces the error

package main

import "net/http"

func main() {
	var h any = http.Header{}
	_ = h
}

This is possibly related to a fixed issue with x/tools/nilness golang/go#58296

I also get this issue on all recent versions of gokart and go versions 1.21.1, 1.22.0, and 1.17.x with the repro above

The solution is not to use gokart - it's no longer maintained
