EDIT :
I add in the server.conf configuration file :
report_disable_sandbox = true
If I installed chromium-libs-67.0.3396.79-1.el7.x86_64, I’ve this output :

But in this topic : Report Generation Error - #11 by marius, @marius said :
“Cool that it is working now for you! We will add more details to the documentation soon. The error regarding libGLES could be ignored, since in headless_mode no graphic acceleration is needed anyways.”
After this, the report generation works.

EDIT 2:
Without the chromium libs package, the report generation works but the logs are differents:
