Error creating projects in the business central

Hello everybody,

This problem concerns about 7.21 and 7.23 versions. I tryed both and I got same problem.
I downloaded jbpm pack in https://www.jbpm.org/
I unzipped it in /usr/share/jbpm firstly, and also in /opt/jbpm (I tryed in both Paths) after I got the problem. I gave to both Paths+777 permissions.
I started the server using standalone.sh -b 0.0.0.0

When I logged into Business Central using web browser, I tryed to create a new project. I got an error (see attached picture). I also create a new Space and tryed again but with same result.
I can´t reach the problem I got.

Please, find attached logs and picture about the error.
Any idea?

Note: If it can helps, Im reaching the CentOS server through VPN, but it doesn´t seem to be a network problem.

Thanks in advance,

Best Regards,
Jacobo
