ReferenceError: TextEncoder is not defined

[eduardoltorres]

What version were you using?

https://github.com/LearningLocker/learninglocker/releases/tag/v7.1.1

What steps can we follow to reproduce the behaviour?

Basically the steps in https://learninglocker.atlassian.net/wiki/spaces/DOCS/pages/622596/Installing (documentation update of Aug 04, 2022).

More specifically...

Using Ubuntu 18.04.6 LTS:

1. curl -o- -L https://raw.githubusercontent.com/LearningLocker/deploy/master/deployll.sh > deployll.sh && bash deployll.sh
2. sudo su learninglocker
3. pm2 status displays that xAPI "errored" (see screenshot below of output table)
4. pm2 logs xAPI include the following error for both 4|xAPI and 5|xAPI repeated times (e.g. even logging pm2 logs --lines 4000)

What is the actual behaviour?

What is the expected behavior?

The expected behavior is for all processes to start with an "online" status.

Is there any additional information that will help us replicate/understand the problem?

I did some digging and it seems to be related with node's version:
jsdom/whatwg-url#209
Automattic/mongoose#10638

The only thing that fixed it for me was:

1. Following this suggestion https://stackoverflow.com/a/69287561/20588311
2. Changing from the installed node version (10.24.1; i.e. the one that learning-locker installed during deployll.sh execution) to node 16.8.1.
3. Running yarn

There is a solution in this issue #1625
Adding a "missing" require.
