func main() {
original := []byte(`null`)
patchJSON := []byte(`[{"op": "add", "path": "/version", "value": "0.2.0"}]`)
patch, err := jsonpatch.DecodePatch(patchJSON)
if err != nil {
panic(err)
}
options := &jsonpatch.ApplyOptions{EnsurePathExistsOnAdd: true}
modified, err := patch.ApplyWithOptions(original, options)
