Panic when editing a message

[CodeExplorerX]

Panic occurs when editing a message. The code was used as an example from the repository page. go version: go version go1.22.4 windows/amd64 Code:

Debug log: ` "edited_message":{"message_id":106,"from":{"id":23432432,"is_bot":false,"first_name":"\u1160","username":"example_user","language_code":"en"},"chat":{"id":24234232,"first_name":"\u1160","username":"example_user","type":"private"},"date":1720134098,"edit_date":1720134108,"text":"/edit","entities":[{"offset":0,"length":5,"type":"bot_command"}]}}]}' panic: runtime error: invalid memory address or nil pointer dereference [signal 0xc0000005 code=0x0 addr=0x48 pc=0xb23a40]

Additions: When you restart the bot after a panic, panic occurs again and the bot cannot work. To eliminate panic, changing the token helps.

EditMessageText works for me https://github.com/go-telegram/bot/tree/main/examples/edit_message Can you provide your code?

I also met this problem, here's the solution.

Check out the example code here. The difference is, line 35 checks whether update.Message is nil.

You can do that in your default handler too, I think that will work. My approach is adding a middleware that checks update.Message, and it worked.

Here's my middleware

func nilChecker(next bot.HandlerFunc) bot.HandlerFunc {
	return func(ctx context.Context, b *bot.Bot, update *models.Update) {
		if update.Message == nil {
			return
		}
		next(ctx, b, update)
	}
}
