"tag_name" is not successfully parsed

[Bellisario]

I was trying to parse from latest GitHub releases, but I had a problem parsing "tag_name". Is this supported? Am I doing something wrong?

Here is a piece of what I'm trying to do:

var latestRaw = gjson.Get("{tag_name: \"1.1.0\"}", "tag_name").String()
// latestRaw is an empty string
