Error: 403: Forbidden: bot was blocked by the user about telegram-support-bot

[bostrot]

Just experienced something similar with this addition:

bot002    | === UNHANDLED REJECTION ===
bot002    | 'Sat May 15 2021 21:04:25 GMT+0000 (Coordinated Universal Time): Error: 403: Forbidden: bot was blocked by the user\n' +
bot002    |   '    at /bot/node_modules/telegraf/core/network/client.js:281:17\n' +
bot002    |   '    at processTicksAndRejections (node:internal/process/task_queues:94:5)'

It continues after restarting the bot so it probably hangs with the telegram polling and crashes before marking it as read..

I guess we need some checks whether the bot can actually write the user and still mark the message.

EDIT:

I could not reproduce that the bot works only with nodejs v10.24.1. Are you missing some dependencies? What is your log? (I tested including v12.22.1, v14.16.1, v16.2, also some others in earlier stages so I guess you are missing something..)

This started happening after the previous update. Before that, it was put without problems. I install NVM, and then go through the node js versions. In all cases, except for version 10, errors appeared. Perhaps you are right and it's about dependencies.

Thank you for your help and quick response!

If you just delete the bot, then when you reply to the user, the message comes without problems. If the "stop bot" checkbox is checked when deleting a bot,then this is the error.

Could you share some logs or the error messages?

I will try to create a check if the bot is blocked and see if it still does the same.

Okay, I'll do it soon

Sometimes your application throws an error of the "Error" type, after which it can continue to work, or it can "hang", and in this case, until I restart, new messages from users do not come. Today there was an error: "b4Error". In debug.log, they are usually not present, or they are also referred to simply as "Error". If I run the app in dev mode, will I collect the errors in a more detailed format?

[bostrot]

If it shows only "Error" then the actual error message is empty which makes it very hard to debug. Do you know what happened before it showed the message?

Running in dev mode could give you more details but I can't say for sure that it shows the actual error message then.

Looked into it a bit closer and it seems that commit 9f44bd6 (from issue #52) is the reason:

ctx.reply('Message is not sent due to an error.');

The bot tries to send an error message to the user but as it is blocked it gets into a loop..

[bostrot]

Commit 27a707f should be a hotfix for now (for Forbidden: bot was blocked by the user) which catches any error that is thrown by sending an error message to a user that has blocked the bot. Could you try it?

Also regarding the error messages: npm run dev should give you a little more detail about where they come from.

Thanks! I will test it.

Updated normally, when the bot is blocked, the app no longer crashes

Thanks for testing and providing the log.

This seems rather like a better-sqlite3 error. Could you try installing it seperately?

npm install better-sqlite3 --save

in your working directory.

This is a better-sqlite3 build error. Try installing build tools sudo apt-get install build-essential and if that doesn't work check out their github to find a solution.

@CodeQuit This is already fixed.

You get the message when the users blocks/stops the bot. There is nothing you can do once that happened.
