Describe the bug
LMS Plugin crashes when pulling data.
:_update_plugins:465 :ERROR - <class 'library.Plugin.Plugin'> crashed while updating: 'str' object has no attribute 'get'

This results in the update loop stalling out and no updates being pushed to the display

This is related to a bug in QueryLMS and should be resolved by reinstalling PaperPi or manually updating the QueryLMS library.

To manually update the QueryLMS library:

1. Switch to the root user: sudo su - * see note below
2. Change to the paperpi install directory: cd /usr/local/paperpi
3. Update querylms to 0.2.5.0: pip install QueryLMS==0.2.5.0
4. Drop out of sudo
5. restart paperpi daemon sudo systemctl restart paperpi-daemon

• Note: this should be the paperpi user, but something is wrong with the installer. See I PaperPi installer should create virtual env as root #162
