etherpad-lite: systemd service file for v2.0 (was: unexpected string in JSON after upgrade to v2)

Describe the bug When running etherpad for the first time after update with sudo -u etherpad bin/run.sh, it complains about an unknown string in the settings, yet I can’t see any difference to the template in the mentioned place.

We are coming from v1.9.2 (as far as I can tell). I had git to pull the latest versions and checked out to tags/v2.0.1, as we always did with previous updates. For the first run I had to run bin/run.sh it as root as otherwise it couldn’t access /usr/local/lib/node_modules otherwise (and I don’t think having the etherpad user own that directory is the best solution). Of course afterwards I re-owned all files in the etherpad directory by the etherpad user. It threw some fatal error - maybe because of tidyHtml setting still present, who knows - so I went through the whole settings.json, compared to the settings.json.template and made the appropriate changes. Yet running the etherpad from shell still results in

Or as the whole output:

Here is the current settings.json we use, obviously with passwords redacted: settings.json

Now I don’t know how json interpreters read positions. But the only two positions that should be possible for position 129 should be either

{
  /*

or

"favicon": null,

But in both cases there’s no difference, even diff can’t find one there. So what exactly is the issue?
