Support for Juniper (juniper.master)

I am trying to install Rocket chat Xblock on Juniper version. But I am facing following error:

2020-09-14 11:18:35,374 WARNING 6231 [xblock.plugin] [user None] plugin.py:147 - Unable to load XBlock 'rocketc'
Traceback (most recent call last):

    except KeyError, xblock_settings_error:
                   ^
SyntaxError: invalid syntax

It seems it is not compatible with Python 3.5. Is the community working on its upgrade ?
