Sikuli errors on RHEL 8 virtual machine

Hi,
On a RHEL 8 virtual machine, I am able to launch the sikuli IDE, by running the runsikulix script.
However, when I try to run sikuli without the IDE, it crashes as soon as it arrives at a " if exists (image.png)" statement, with the following error message:
#

Is there some library I might be missing or is Sikuli incompatible with a virtual RHel 8 machine ?
