Notifications are not working

[SH-Stark]

Hello, when starting the bot I get some errors then the bot works normally.

The notifications system doesn't work tho, I don't receive a buy or sell notification. My apprise.yml is configured correctly, and with the BTB-manager I can interact with "Begin" or "/start".

Here is the log I get when running the bot:

➜  binance-trade-bot git:(master) ✗ sudo python3 -m binance_trade_bot

During handling of the above exception, another exception occurred:

Any idea? thanks

My apprise.yml under the config file in case :)

Not sure, but this doesn't seem to be a bug with the bot (as it's working for everyone) but rather with your own setup. Please consult our Discord channel for issues of this sort. Thanks!

Just to answer, I was having this issue as well. The short answer is that python 3.9 appears to make some changes to asyncio which impact systems including Mac and some distros of linux. I recommend downgrading your python to 3.8 to get rid of the error. This problem will also impact the asyncio function calls made by unicorn-binance-websocket-api in https://github.com/edeng23/binance-trade-bot/pull/328
