Error while deserializing response (getUpdate)

[Migsi]

This issue doesn't belong to the Minegram itself, it seems to be an error of the used json-lib.
When trying to deserialize updates the following error appears:

Please, @Migsi, could you test your bot plugin with this version? Thanks!

[Migsi]

Thank you for the update! I'll test it as soon as possible!

[Cadiducho]

Thank you for testing! I hope it will work and release new version with this fix and new inline bots to Spigot, in order to check about Gson later ;)

[Migsi]

After testing it today, the issue remains the same :/ Could it be my fault?

This is the code I use to test it:

`
public void onEnable() {
telegramBot = new TelegramBot("xxxxxKEYxxxxx", this);
try {
telegramBot.sendMessage(xxxUserIDxxx, "Hi! This is a test onEnable");
} catch (TelegramException e) {
System.out.println("Couldn't send any message!");
}
new BukkitRunnable() {

        @Override
        public void run() {
            try {
                List<Update> updates = telegramBot.getUpdates(xxxUpdateNrxxx, 100, 0);
                if (!updates.isEmpty()) {
                    getLogger().info(updates.get(0).getMessage().getText());
                }
            } catch (TelegramException e) {
                e.printStackTrace();
                System.out.println("Could'nt get bot instance!");
            }
        }
    }.runTaskTimer(this, 0, 500);

    getLogger().info("Test plugin recieve enabled");
}

`

EDIT: Sorry for bad format, but the editor seems to not recognize the backticks -.-'

[Cadiducho]

No, is not your fault. Yesterday I reproduced the bug and i'm triying to fix it (it is still alive D:! ) but is really really annoying. I rewrited completly the getUpdates() method, not using jackson mapper at all, and I discover that the problem comes from ['Message' object.]

...
Update update = new Update();
                update.setUpdate_id(jsonUpdate.getInt("update_id"));
                if (jsonUpdate.getJSONObject("message") != null) 
             ------> update.setMessage(mapper.readValue(jsonUpdate.getJSONObject("message").toString(), Message.class));
                if (jsonUpdate.getJSONObject("inline_query") != null) 
                    update.setInline_query(mapper.readValue(jsonUpdate.getJSONObject("inline_query").toString(), InlineQuery.class));
...

(https://github.com/Cadiducho/Minegram/blob/master/src/com/cadiducho/minegram/api/Message.java)
The funny fact is that the logs said something about a conflict with 'config' property, and that class (and any other, by the way) have a config variable.It's really strange.

So I really don't know. I can't fix it (yet)... I'll try Gson's mapper... sorry for the inconvenience!

[Migsi]

No problem, I'm in no hurry with my project. It's fine for me to see that you're trying to solve this! :) It's anyways a nice job you're doing, this API is pretty cool :)

What belongs to this problem, I must sincerly say that I don't have enough java skills to help you that much :/ And the fact I don't know anything about the Jackson lib doesn't make this better... I'll try to read your sources and, if I find anything helpful, give you advises as good as I can. :)

[Cadiducho]

Good news! Gson has simplified my code a lot and... getUpdates() method is working! All builders of objects have been changed, and I will test it before upload new version. In a few hours it will be uploaded in Spigot, Github and Maven repo

[Migsi]

Thank you for fixing this! :)

Already late? :(
I have had same issue on my another Jackson based project. and I resolved it with this (
cause of this problem) and answer.
It's because of Jackson's issue! 😢

[Cadiducho]

Yes, is too late, I use gson now :(
But thanks for the help! ^^
