Code which gives the ability to reproduce above behavior:

package main

func main() {
	obj := make(map[string]interface{})
	obj["schema"] = make(map[string]interface{})

	if _, ok := obj["schema"].(map[string]interface{})["items"]; ok {
		obj["schema"].(map[string]interface{})["version"] = 1
	}
}

Originally it was spotted during usage of golangci-lint and reported to in issue golangci/golangci-lint#1278

Cheers!
