Some users experiments issues with Kali. This step works well on other OS.

Normally, the function writeFileSynccreates file if it not exists, so can you check permissions and owner of /home/kali/.dexcalibur folder ?

Did you try a chmod 666 /home/kali/.dexcalibur ?

Thank you very much for your time and effort!

After I manually created ~/.dexcalibur (mkdir ~/.dexcalibur), I'm now facing the following error:

[Object: null prototype] { _t: '1614174667806' }

Red text into console is not an error message if it not starts by [ERROR] as mentionned by @cryptax, i should change this color.

In your case, the message warns you an external process spawned (java).

Did you restarted dexcalibur ?

[BreakfastSerial]

I restarted dexcalibur after the changes.

I just tried to chmod -R 777 ~/.dexcalibur, after dexcalibur now starts successfully.

Oddly enought chmod 666 corrupted the file/permissions.

Thank you!

Thank you for your documented issue on Kali OS, it allows me to write some lines into installation guide for Kali's users
