Hi Majo, It's unclear how you've obtained that error. But, the NullPointerException to me almost seems to imply that DSpace isn't running, or something is incorrect in your Handle configuration. Maybe if you provided the steps you've taken to get that error, it'd help others provide you with more advice.
As far as I'm aware, it should be possible to run the Handle Server itself with a "fake" handleprefix. However, it will not resolve "https://hdl.handle.net/"; URLs until you have a valid prefix registered with that service. (If I'm wrong about that, I hope someone else will correct me. I'll admit, I'm not sure if this changed in more recent versions of the Handle Server software.) Overall, you don't need to run the Handle Server in DSpace unless you want to generate permanent "https://hdl.handle.net/"; URLs for every object.
