Servlet execution error adding entities to a project
Hi,
We want to add entities to a project but we can´t. We get an error when we try to add a thing to the project in the entities area.
This is the error:
[L: ERROR] [O: c.t.s.a.AuthenticationFilter] [I: ] [U:] [S: ] [P: ] [T: https-jsse-nio-443-exec-3] Servlet execution threw an exception
But we can change the project if we edit the thing with the same user.
We are using 9.1.3 version.
Does anybody know what could be the cause of this problem?
Thanks in advance.
