Can not return value when a period/dot is in key even if escaped

[eexbee]

go1.18.1 linux/amd64
gjson version 1.17.1

sample json:

{
"timestamp": "2024-04-17T05:39:04",
"MAIN.uptime": {
    "description": "Child process uptime",
    "flag": "c", "format": "d",
    "value": 320
  },

  "MAIN.sess_conn": {
    "description": "Sessions accepted",
    "flag": "c", "format": "i",
    "value": 8
  },

  "MAIN.sess_drop": {
    "description": "Sessions dropped",
    "flag": "c", "format": "i",
    "value": 0
  },
...
}

I want to retrieve the value inside MAIN.sess_conn, I've tried all this and it prints empty string:

fmt.Println(gjson.Get(json, gjson.Escape("MAIN.sess_conn")))  // prints blank line
fmt.Println(gjson.Get(json, `MAIN\.sess_conn.flag`))  // prints blank line
fmt.Println(gjson.Get(json, `MAIN\.sess_conn.value`).String())  // prints blank line

Even the Exists method returns false

fmt.Println(gjson.Get(json, `MAIN\.sess_conn.value`).Exists())  // prints false
fmt.Println(gjson.Get(json, `MAIN\.sess_conn`).Exists())  // prints false

It all works for me.

json := `{
	"timestamp": "2024-04-17T05:39:04",
	"MAIN.uptime": {
		"description": "Child process uptime",
		"flag": "c", "format": "d",
		"value": 320
		},
	
		"MAIN.sess_conn": {
		"description": "Sessions accepted",
		"flag": "c", "format": "i",
		"value": 8
		},
	
		"MAIN.sess_drop": {
		"description": "Sessions dropped",
		"flag": "c", "format": "i",
		"value": 0
		}
	}
}`
fmt.Println(gjson.Get(json, gjson.Escape("MAIN.sess_conn"))) // prints blank line
fmt.Println(gjson.Get(json, `MAIN\.sess_conn.flag`)) // prints blank line
fmt.Println(gjson.Get(json, `MAIN\.sess_conn.value`).String()) // prints blank line

// Output:
// {
// 		"description": "Sessions accepted",
// 		"flag": "c", "format": "i",
// 		"value": 8
// 		}
// c
// 8
