Module won't show up - no apparent errors.

[Reuben]

I just finished installing this module after trying and failing to install eouia / bugsounet's MMM-Assistant Mk2. I got further with this module, to the point that running /home/pi/env/bin/python3 -u assistant.py actually work, google assistant responds to me saying 'OK Google' and it is all linked up to my account.
I have put the module into the config file (I've entered the keys):

And I have set the module to autorun:

However, when I start the mirror google will not respond and there is no icon. I've checked for errors by running in dev mode:

I must be honest, I have no clue what [2020-04-26 15:31:25.831] [ERROR] (node:6232) [DEP0066] DeprecationWarning: OutgoingMessage.prototype._headers is deprecated [2020-04-26 15:31:25.832] [ERROR] (node:6232) [DEP0066] DeprecationWarning: OutgoingMessage.prototype._headers is deprecated
means, although I did notice in the Google SDK a warning -

Warning: The Google Assistant Library for Python is deprecated as of June 28th, 2019. Use the Google Assistant Service instead.

However, I assumed this was a non-issue as it still ran using the python script
And this is what I get in the web console:

Other modules I am running are: MMM-Reddit and MMM-Screencast. MMM-Reddit is also not working, as you may notice, so there may be something in common that's causing them to fall over, or a conflict.

Anyway, any help would be appreciated as I'm stumped here.
