Adding --server-settings data/server-settings.example.json to the arguments did the trick for me

Worked for me too!

I know this one is old, but I just found it.

The reason it don't like your own server-settings.json file, is that you proberly have an missing tag inside it, like an , or something else.

Find an online json validator and put your server-settings.json file into it and it will most likely find an error in it.
