Brunt component install error - any advice?

Hi all.
my brunt blind engine works, but doesn’t get picked up by HASS. is installed, in the HASS venv on hassbian.
Can anyone decode the following log error, or offer any troubleshooting advice?

Additional information:

Did you add the cover to your configuration file according to this information?

thanks @Pippyn - yes my config includes the brunt cover, and passes validation.

But what do you mean by this?

Did you add a custom component?

no i didn’t - brunt is an official component.
i referenced because another user had a hass error with the component, but it was because wasnt installed:
i have checked and it is installed, so the problem lies elsewhere.

this is solved - the problem was to do with the minimum python version. fixed in 0.77

Can anyone advise on this please?
