Respond to clicks / This request will never generate a response

[dandaka]

Now

Documentation here https://grammy.dev/plugins/keyboard.html#responding-to-clicks

This does not work for me

bot.callbackQuery("click-payload", async (ctx) => {
  await ctx.answerCallbackQuery({
    text: "You were curious, indeed!",
  });
});

Cloudflare Workers gives 500 with the error "This request will never generate a response"

Is it a bug in the documentation?

This works for me

bot.callbackQuery("click-payload", async (ctx) => {
  await ctx.reply("You were curious, indeed!");
});

[KnorpelSenf]

Does this only happen on cloudflare workers?

[KnorpelSenf]

Is it a bug in the documentation?

No. The code is correct.

[dandaka]

Do you want me to create a Workers project to reproduce the issue?

[KnorpelSenf]

We certainly need to be able to reproduce this if we should fix something, yes.

I'm not really sure how this is even possible, because grammY works the exact same way for both code snippets, so the error must somehow depend on content of the JSON payload in the request. This can hardly be the case.

It would be even more helpful if you are able to reproduce this locally somehow, rather than on CFW. If you manage to do this, please share the instructions.

[dandaka]

Is it possible to run Telegram webhooks locally? I am keen to try.

[KnorpelSenf]

Is there no way to run your CF Workers application locally?

Otherwise, you can always use tools like ngrok to tunnel the requests to your machine.

Also, you can change your code to use long polling instead of webhooks.

[dandaka]

Yep, there is a way to run Workers locally. I am just curious about how to ask Telegram to send webhooks to a local machine. Will check ngrok.

[KnorpelSenf]

You can also just use curl or Postman to send artificial updates to your bot. A number of example updates are linked at the top of https://grammy.dev under Resources > Example Updates.

[KnorpelSenf]

Are you able to reproduce this now?

[dandaka]

Working on it, combining a repo that you can deploy and reproduce the issue.

[dandaka]

On localhost, the script loads indefinitely and crashes with an "out of memory" error.

[KnorpelSenf]

That is very strange. Looking forward to seeing the code …

[dandaka]

This is the code. When I reply with a simple message, it works well. When I try to use answerCallbackQuery, I see the following errors on Workers (not on local env)

When I use ngrok to send requests to a local machine, I get super long loading and error in local machine logs:

[KnorpelSenf]

Try pre-setting the bot info.

new Bot(token, { botInfo: /* result of `getMe` */ })

[dandaka]

1. Pre-set the bot info.
2. Launch the app.
3. Open the URL in localhost console
4. Still hangs with no response for a long time.
5. Can see a new error in logs:

[KnorpelSenf]

It seems like cloudflare shipped a new version. Can you simply try again?

[dandaka]

What exactly was updated? I have updated wrangler to the latest wrangler 2.11.0. Same problems, script not working.

[KnorpelSenf]

Can you share the exact curl command that you use to test your bot?

There is a person who is more familiar with CFW but they do not have a GitHub account. They are a member of https://t.me/grammyjs, however. Asking the same question in the group chat may be a more efficient way to resolve this. Feel free to just share a link to this issue, we'll know.
