[BUG] raspberry: async utils - Unhandeld error in background task: Connector loopring class not found

RobJah commented 3 years ago

Describe the bug When i run my freshly installed hummingbot on my raspi4B i cant seem to get past the point where i insert the api key for my loopring account. I get the error 'async utils - Unhandeld error in background task: Connector loopring class not found' Also I get another error on start up, but im not sure if it is related: hummingbot_cli - Unhandeld error in prompt_toolkit: [SSL: KRB5_S_INIT] application data after close notify (_ssl.c:2609)

Steps To Reproduce I did every thing mentioned in this guid exept for the Multiple Nodes part: https://hummingbot.io/blog/2020-07-deploying-hummingbot-on-a-raspberry-pi/

Here are the steps to reproduce the issue (see attachments in the section below):

Try to connect a loopring account, get stranded at the api key ...

Release version 0.32.0

Attachments didnt even get to the config

the error first appears on version 0.31.0 this is due some new changes into the hummingbot
this is not exchange specific
the error will show without doing anything.
the error doesn't show on docker build for raspberry pi only on source build
still able to run a strategy but bot will throw some errors
the raspberry pi hummingbot is still on beta.

Hi Patrick,

Thanks for your respons. I think the main problem i'm experiencing is the other error i mentioned: async utils - Unhandeld error in background task: Connector loopring class not found

Do you have any suggestions about that error and what i possibly did wrong to get it? Because i just cant seem to get past the insertion of my api key. The strange thing is that when I exit the hummingbot and restart it to retry connecting the loopring account i do get the message 'do you want to delete your current api key?' So eventhough im not getting past the api key insertion (it just keeps asking for the api key no matter how often i insert it), it does save something.

So I created a bot, adjusted the pure market making config to my usual settings, and entered the 'start' command, but all it says is "Preliminary checks:" but nothing follows, no orders get placed.

Thanks in advance!

**Edit:

when i enter the balance command i get the same error (async utils - Unhandeld error in background task: Connector loopring class not found) and no balance is shown, only 'Updating balance, please wait...'
When i enter the connect command i dont get the list of exchanges, only 'Testing connections, please wait....'**
