Thanks for your long answer Scott.
seemed that I had a wrong x server configuration. I setup a new user and
now it works. I think you can't use x or the paraview web stuff as a
root user.

Hi Daniel,
I have several thoughts after reading your email, though I'm not
sure how helpful they may be. First, the error you reported doesn't
sound (to me) like the typical error you might see when you do not
have your graphics environment configured properly. I assume that
even without a display you are setting up an X server and making sure
to set the DISPLAY environment variable before running the script?
Even though you are not using EC2, some of the information at the link
below could pertain to your situation:
http://kitware.github.io/paraviewweb/docs/guides/graphics_on_ec2_g2.html
hopefully that gets you pointed in the right direction.
Another thing to note: I don't believe that the pv_web_visualizer
python script is included in ParaView anymore, though I don't recall
exactly when that moved (it appears you are using version 5 or
above). Now the web side of ParaView has moved into various other
github repositories:
Core Libraries: https://github.com/Kitware/paraviewweb
Web Visualizer Application: https://github.com/Kitware/visualizer
These days you will find the equivalent of the pv_web_visualizer.py
script in the above repo (located under "server/pvw-visualizer.py").
However, if you do indeed have the python script in the location
stated in your email, then I'm not sure what could be causing the
apparent json error you mentioned. Normally though, one might have
provided some arguments to that python script in the use case it seems
you are targeting, although perhaps you just left them out when
composing your email. For example, if you did not provide a
"--content" argument, specifying the path to the static content you
are serving, are you managing that another way?
Feel free to post more information such as the complete command
line you are invoking, how you are connecting from your browser
(assuming you get that far), or perhaps more error output if there is any.
Hope this helps.
Cheers,
Scott

Hi,
I try to get pvweb to run on my server without monitor (but intel
graphics card). Seems not as easy as I thought. I run e.g. the
visualizer:
/root/salome_meca/V2016/prerequisites/Paraview-v501_EDF/bin/pvpython
/root/salome_meca/V2016/prerequisites/Paraview-v501_EDF/lib/paraview-5.0/site-packages/paraview/web/pv_web_visualizer.py
and I get the error:
terminate called after throwing an instance of 'Json::LogicError'
what(): in Json::Value::find(key, end, found): requires
objectValue or nullValue
any ideas?
