GrammyError: Call to 'setMyCommands' failed! (404: Not Found)

[devsheva]

I'm developing a simple bot and using Jest to run some unit tests. I looked at the example on official docs, but it didn't use setMyCommands api, so it wasn't really my case.

I'm getting GrammyError: Call to 'setMyCommands' failed! (404: Not Found)when running tests.

So basically is just cause I'm using "test token" but it still hits Telegram? So how should I test it?

[KnorpelSenf]

Your code is executed in the wrong order if you expect that the transformer is installed before the API call is performed. Naturally, the module is loaded before the tests are run, and your API call already happens on module load but the transformer is installed on test execution.

If you do this, you need to use a valid bot token as described at the link above.

Alternatively, you can reorder your code to install the transformer first.

[devsheva]

Alright, I think I'll opt to reorder the code since I want to do tests without hitting external API. But my last question regards this is, I can wrap the setMyCommands api call in a function, but when should I call this one then?

[KnorpelSenf]

In your beforeAll hook maybe?

[devsheva]

That would make sense, but I mean in my code in general. Does setMyCommands need to be called in a specific order or that's indifferent? Of course before starting the bot i guess

[KnorpelSenf]

It is irrelevant when you call it as long as the transformer is installed before that :)

[devsheva]

No ok I totally agree with you. Maybe I didn't explain what I meant well, but basically I'm just asking about the order in the running general code, not the tests concern one

[KnorpelSenf]

If we're not talking about tests, then my personal opinion is to never call setMyCommands for global commands from bot code. Instead, call it in your deployment script, or maybe just configure it with @BotFather directly.

I think that it only really makes sense to use the method when you apply scopes. For example, when the bot joins a chat, it could set the commands for that specific chat.

[devsheva]

Gotcha, I didn't think about it in that way. Really appreciate the answer and the fast replies. I'll close this as completed
