Python Telegram Bot Webhooks Error
Hey, I'm deploying a telegram bot (python-telegram-bot library) with a server/webhooks. It works locally, but not when deployed to railway. I'm getting an error on this line it seems:
await application.bot.set_webhook(url=f"{URL}/telegram", allowed_updates=Update.ALL_TYPES)
Logs attached below.

have you read the deployment logs? doesnt really look like an issue caused by railway, looks more so like a code issue
It works locally tho. Must be an issue with HTTP/ports/webhooks/etc.
working locally does not rule out a code issue
I see. Well ive tried a bunch of stuff and cant find any updated examples on the internet for hosting a python telegram bot on railway. Posting my server setup code here if anyone has ideas.
async def main() -> None:
"""Set up PTB application and a web application for handling the incoming requests."""

# and hence we don't need an Updater instance
application = (
Application.builder().token(TOKEN).updater(None).context_types(context_types).build()
)
# register handlers
application.add_handler(CommandHandler("start", start))
application.add_handler(CommandHandler("add", add))
application.add_handler(TypeHandler(type=WebhookUpdate, callback=webhook_update))
# Pass webhook settings to telegram
await application.bot.set_webhook(url=f"{URL}/telegram", allowed_updates=Update.ALL_TYPES)
# Set up webserver
async def telegram(request: Request) -> Response:
"""Handle incoming Telegram updates by putting them into the
update_queue"""
await application.update_queue.put(
Update.de_json(data=await request.json(), bot=application.bot)

return Response()
async def custom_updates(request: Request) -> PlainTextResponse:

await application.updatequeue.put(WebhookUpdate(data=data))
return PlainTextResponse("Thank you for the submission! It's being forwarded.")

We currently support two ways of processing bot updates, getUpdates and setWebhook. getUpdates is a pull mechanism, setwebhook…
