Returning array like json with Fiber, Golang

I have a table with columns token, user_id and last_seen in my databse

The task is to send all of them with my app when it gets a get request

Fiber, Golang:

	type sessionsInfo struct {
		token     		string
		user_id      	int
		last_seen 		string
	}
	app.Get("/testA", func(c *fiber.Ctx) error {
		logMsg("GET /testA")
		var sessions sessionsInfo
		execQuery := `select * from sessions`
		rows, err := db.Query(execQuery)
		if err != nil {
			fmt.Println(err)
			return c.SendStatus(418)
		}
		var sessionsArray []sessionsInfo
		for rows.Next(){
			rows.Scan(
				&sessions.token,
				&sessions.user_id,
				&sessions.last_seen,
			)
			sessionsArray = append(sessionsArray, sessions)
		}
		defer rows.Close()
		fmt.Println(sessionsArray)
		c.JSON(sessionsArray)
		return c.SendStatus(200)
	})

The strange thing is that i see correct array in console, matching 100% my data in DB

but with some reason when i look at answer's body i see json that has 25 empty sub-jsons (i dunno how to name it correctly, lmao), like this

[
    {},
    {},
    {},
    {},
    {},
    {},
    {},
    {},
    {},
    {},
    {},
    {},
    {},
    {},
    {},
    {},
    {},
    {},
    {},
    {},
    {},
    {},
    {},
    {},
    {}
]

The same count as it should be, but empty.
The result should be something like this

[
    {
        "token": "be0e6163-ce2c-4ac3-5349-ff3b34a51c37",
        "id": "1",
        "last_seen": "2021-10-21T17:50:42.308751Z"
    },
    {
        "token": "6c4f21f1-dc00-4975-6fe2-c69d14328099",
        "id": "2",
        "last_seen": "2021-10-21T17:51:27.963031Z"
    }
    ...
    ...
    ...
]

How can i fix this? What am i doing wrong?

Export the types:

type sessionsInfo struct {
    token           string
    user_id         int
    last_seen       string
}

To:

type SessionsInfo struct {
    Token           string `json:"token"`
    User_id         int `json:"user_id"`
    Last_seen       string `json:"last_seen"`
}
