Error regarding source map in browser console

[Ithanil]

Describe the bug
I've updated our testing ScaleLite to use the bbb-playback packages from jammy-300 and everything works fine, except that I noticed the following message in browser console:

Source map error: Error: JSON.parse: unexpected character at line 1 column 1 of the JSON data Resource URL: https://MY-FQDN/playback/presentation/2.3/static/js/main.340e9e57.js Source Map URL: main.340e9e57.js.map

Is this message benign?

To Reproduce
Steps to reproduce the behavior:

1. Use files from current jammy-300 repo
2. Start playing a presentation recording (e.g. from Greenlight)
3. Observe the browser console
