Thanks for your long answer Scott.<br>
<br>
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.<br>

<div>Hi Daniel,<br>
<br>
</div>
<div> 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:<br>

<br>
</div>
<div>hopefully that gets you pointed in the right
direction.<br>
<br>
</div>
<div> 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:<br>
<br>

<div>Core Libraries: <a moz-do-not-send="true"

</div>
<div>Web Visualizer Application: <a
moz-do-not-send="true"
href="https://github.com/Kitware/visualizer">https://github.com/Kitware/visualizer</a><br>
<br>
These days you will find the equivalent of the
pv_web_visualizer.py script in the above repo (located
under "server/pvw-visualizer.py").<br>
<br>
</div>
<div> 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?<br>
</div>
<br>
</div>
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.<br>
<br>
</div>
Hope this helps.<br>
<br>

<div>Cheers,<br>

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:<br>
<br>
/root/salome_meca/V2016/prereq<wbr>uisites/Paraview-v501_EDF/bin/<wbr>pvpython
/root/salome_meca/V2016/prereq<wbr>uisites/Paraview-v501_EDF/lib/<wbr>paraview-5.0/site-packages/<wbr>paraview/web/pv_web_visualizer<wbr>.py<br>
<br>
and I get the error:<br>
<br>
terminate called after throwing an instance of
'Json::LogicError'<br>
what(): in Json::Value::find(key, end, found): requires
objectValue or nullValue<br>
<br>
<br>
any ideas?<br>
<br>
