** Using WeBWorK **

I am at a loss here. I upgraded to 2.17 from 2.16 (Ubuntu 20.04).  I thought I was installing hot-fixes but inadvertently upgraded to 2.17 on a production server...But I digress. 

With 2.16, tikz worked fine and all rendered well. However, now the web pages are not rendering correctly at all and throwing a tikz error (see below), and students are not able to complete their work.  

The server that I upgraded looks like this: https://webwork.unbsj.ca/webwork2

I followed the upgrade instructions in the release notes, all seemed to go well except for errors when running npm install in htdocs.

npm install (in htdocs) errors:
