In Node 6, running Karma gave the following warning:
Error during loading "/home/runner/work/backbone/backbone/node_modules/karma-sauce-launcher" plugin:
Unexpected token function
I had no such error running karma after installing karma-sauce-launcher
locally in Node 14, so this upgrade might fix some things.
We are not exactly in the business of supporting old Node versions, so
this should be relatively painless.
If I understand the documentation correctly, it is not strictly
necessary that these variables be read from the workflow file; they
may also be read directly by the target processes.
