Error in MessageReactionCount Struct

[TheFiordi]

Hello,

While using the library, I encountered the following error:
elebot: json: cannot unmarshal array into Go struct field MessageReactionCount.Result.message_reaction_count.reactions of type telebot.ReactionCount

After investigating, I found that the output of b.Raw("getUpdates", params) in getUpdates() is as follows:

{
  "ok": true,
  "result": [
    {
      "update_id": XXXXX995,
      "message_reaction_count": {
        "chat": {
          "id": XXXXXX,
          "title": "XXXXXXXXXXX",
          "type": "channel"
        },
        "message_id": XXXXX,
        "date": XXXXX,
        "reactions": [
          {
            "type": {
              "type": "emoji",
              "emoji": "❤"
            },
            "total_count": 1
          }
        ]
      }
    }
]
}

As you can see, the reactions field is returned as a list. However, in the library, MessageReactionCount is defined with Reactions as a single ReactionCount, not a slice:

type MessageReactionCount struct {
	// The chat containing the message.
	Chat *Chat `json:"chat"`

	// Unique message identifier inside the chat.
	MessageID int `json:"message_id"`

	// Date of the change in Unix time.
	DateUnixtime int64 `json:"date"`

	// List of reactions that are present on the message.
	Reactions *ReactionCount `json:"reactions"`
}

This mismatch caused the error mentioned above, and the lastUpdateId in Poll() was not incremented, leading to repeated errors and failed updates.

I resolved the issue by modifying the MessageReactionCount struct as follows:

type MessageReactionCount struct {
	// The chat containing the message.
	Chat *Chat `json:"chat"`

	// Unique message identifier inside the chat.
	MessageID int `json:"message_id"`

	// Date of the change in Unix time.
	DateUnixtime int64 `json:"date"`

	// List of reactions that are present on the message.
	Reactions *[]ReactionCount `json:"reactions"` //<- changed to slice
}

With this change, the error is resolved. I suggest updating the MessageReactionCount struct so that Reactions is a slice. If this approach sounds good, I’d be happy to open a PR with the fix.

Thank you!
