Unknown error with no description. Supposed API issue/limit.

[Stisra]

Every single day at roughly around the same time, when I run the code for a chatbot I have been working on (integrated into discord). I get a weird error message with no description or error code:

    event = call.next_event()

This seems to be an API error as I am seeing several lines pointing out the generate content function. And also the fact that creating a new API key seems to resolve the issue (sometimes). Here is the start of my code for where the error seems to first appear:

startTime = time.time()
class Client(discord.Client):
    async def on_ready(self):
        global running, chatSession, priorityChannel
        while running == False:
            try:
                print("ONLINE!!!")
                chatSession.send_message(personality)
                chatSession.send_message(description)
                mainChannel = DiscClient.get_channel("channel id placeholder")
                await mainChannel.send("Coral-Sama is now online :P")
                chatSession.send_message("DO NOT USE EMOJIS IN ANY OF YOUR MESSAGES")
                running = True
            except Exception as e:
                print(f"\033[0;31mError sending prompts: {e} \nTrying again in 15 seconds...")
                time.sleep(15)
                continue
        behaviours.messageLoop.start()

If anyone could point out how this error is happening and how I could fix it that would be great thanks!

Hi @Stisra,

Welcome to Google Cloud Community!

The Error “discord.gateway Shard ID None heartbeat blocked for more than 110 seconds.” This means the Discord bot's main thread is blocked and can't send heartbeats to Discord. 

Here is a workaround and breakdown using asynchronous programming:

• If you are using synchronous code that blocks the main thread, you can move those tasks to their own threads and still use await to wait for them by creating a task with asyncio.create_task.

Please note that the following is an example code demonstration with explanation. For available code templates, check here the documentation.

import discord
import time
import asyncio  # Import the asyncio library


class Client(discord.Client):
    async def on_ready(self):
        global running, chatSession, priorityChannel
        while running == False:
            try:
                print("ONLINE!!!")

                # Move the blocking calls to an async task
                async def send_startup_messages():
                    await chatSession.send_message(personality)
                    await chatSession.send_message(description)
                    mainChannel = DiscClient.get_channel("channel id placeholder")
                    await mainChannel.send("Coral-Sama is now online :P")
                    await chatSession.send_message("DO NOT USE EMOJIS IN ANY OF YOUR MESSAGES")


                # create a task for the startup messages
                await asyncio.create_task(send_startup_messages())
                
                running = True
            except Exception as e:
                print(f"\033[0;31mError sending prompts: {e} \nTrying again in 15 seconds...")
                await asyncio.sleep(15) # Use asyncio.sleep instead of time.sleep

        behaviours.messageLoop.start()

Explanation:

• async def on_ready(self): The on_ready function is now declared as async. This allows you to use await within it.
• async def send_startup_messages(): : A new async method that contains all your blocking chatSession.send_message() and .send() calls
• await asyncio.create_task(send_startup_messages()) : Create a task from your async method. This will run concurrently and allow the on_ready loop to continue running.
• await asyncio.sleep(15): Use asyncio.sleep instead of time.sleep in your except block, as time.sleep is blocking.
