Did the bot send any message to the user when the error occurs? It should be:

✖ Error processing request: Language not found

It means that the specified language code couldn't be found in the locale map.

/switchlangcode command downloads the locale_map.json and then finds the corresponding language file. If no matching language code found, such error would be thrown.

I've tested several command, seems only /switchlangcode can't handle the error.
