Wrong Result on Sync Cron

[guhkun13]

Hi, as I am developing my schedule service, I found that this package does not have any feature to save/persist the job that have been inserted, and so each time the program restarted, the job will also be gone.
So I came up with idea to save the job to the database and in my case, i am using mongodb.
The idea is each time the program restarted, I will do "sync cron" from my db to my cron.
Here is my code:

func SyncCron(myCollection *mongo.Collection) *cron.Cron {

	c := cron.New()

	filter := bson.M{}
	cursor, err := myCollection.Find(context.TODO(), filter)
	if err != nil {
		log.Fatal().Err(err).Msg("failed to find schedule collection")
	}

	records := model.MyModel{}
	err = cursor.All(context.TODO(), &records)
	if err != nil {
		log.Fatal().Err(err).Msg("failed to translate data from db to object")
	}

	for _, record := range records {
		entryIdInt := -1
		if record.IsActive {
			log.Info().
				Interface("record", record).
				Str("record.Url", record.Url).
				Msg("add record")

                       // iterate each record to be sync/saved again to the cron, 
                       // including the record.url (in this case, my command is to call some url using curl GET) 
                       // and the url is mostly unique
			entryId, err := c.AddFunc(record.Spec, func() {
				http.DefaultClient.Get(record.Url)
			})
			if err != nil {
				log.Fatal().Err(err).Msg("cron.AddFunc failed")
			}
			entryIdInt = int(entryId)
		}

		filter := bson.M{"compression_id": record.CompressionId}
		update := bson.M{"$set": bson.M{"entry_id": int(entryIdInt)}}

		updateRes, err := myCollection.UpdateOne(context.TODO(), filter, update)
		if err != nil {
			log.Fatal().Err(err).Msg("scheduleCollection.UpdateOne failed")
		}

		log.Info().Int64("updated count", updateRes.MatchedCount).Msg("update result")
	}

	c.Start()

	return c
}

But the problem is, when the cron running, all the records hit to the same url same with the last one from the db records.
For example I have 3 records, with url to Url-A, Url-B, Url-C.
After sync, all record will hit to Url-C instead of to 3 different URL.

Any help on why this happened will be very much appreciated.
Thank you

[SOLVED]
I found the solution,
it seems that the parameter "cmd" with data type func() need to be returned from another function as a func.

-updated code below

1. new function that will return func()

func createCurlCommand(url string) func() {
	return func() {
		http.DefaultClient.Get(url)
	}
}

2. on line that insert it into new function.

entryId, err := c.AddFunc(record.Spec, createCurlCommand(record.Url))

now the result is right. ID called are unique and different from each other.
