swag init gin. Paths is empty

I'm trying to generate swagger.json by using swag init. Here my code:

package main

import (
	_ "album/docs"
	"context"
	"fmt"
	"net/http"
	"os"

	"github.com/gin-gonic/gin"
	"github.com/jackc/pgx/v5"

	swaggerFiles "github.com/swaggo/files"
	ginSwagger "github.com/swaggo/gin-swagger"
)

// album represents data about a record album.

// @title          Gin Album Service
// @version        1.0
// @description    A albums management service API in Go using Gin framework.
// @termsOfService https://example.dev

// @contact.name  Santosh Kumar
// @contact.url   https://twitter.com/example
// @contact.email example@gmail.com

// @license.name Apache 2.0
// @license.url  http://www.apache.org/licenses/LICENSE-2.0.html

// @host     localhost:8080
// @BasePath /
func main() {
<some code>
}

// GetAlbums godoc
// @Summary  Retrieves user based on given ID
// @Produce  json
// @Router   /albums/ [get]
func GetAlbums(c *gin.Context) {
	<some code>
}

then after <pre> swag init </pre> I have swagger.json file:

{
    "swagger": "2.0",
    "info": {
        "description": "A albums management service API in Go using Gin framework.",
        "title": "Gin Album Service",
        "termsOfService": "https://example.dev",
        "contact": {
            "name": "Santosh Kumar",
            "url": "https://twitter.com/example",
            "email": "example@gmail.com"
        },
        "license": {
            "name": "Apache 2.0",
            "url": "http://www.apache.org/licenses/LICENSE-2.0.html"
        },
        "version": "1.0"
    },
    "host": "localhost:8080",
    "basePath": "/",
    "paths": {}
}

why "paths" is empty? What's wrong with my annotations of GetAlbums?

it seems that I did everything according to the source: https://github.com/swaggo/swag

I found how to fix problem. The wrong json is created when I use <pre> /usr/lib/go-1.18/src/album/swag init </pre>
but when it's
<pre> /usr/lib/go/src/album/swag init </pre>
everything is OK and json is correct. I don't know why it's happens. "go" is just a link to "go-1.18"

To crate a correct swag docs json files please go through the below document, this will solve the issue.
