Error 500 while parsing the XML of the project?
anthony-o opened this issue · 4 comments
I've created a qgis-server with the following docker command docker run -it --name qgis_server -v ${HOME}:/home/${USER} -v /tmp/.X11-unix:/tmp/.X11-unix -v /dev/shm:/dev/shm -e DISPLAY=unix$DISPLAY -e QGIS_PROJECT_FILE='' -e QGIS_LOG_FILE='/tmp/qgis.log' -e QGIS_SERVER_LOG_FILE='/tmp/qgis_server.log' -e QGIS_SERVER_LOG_LEVEL=0 -e QGIS_DEBUG=0 -p 8080:80 kartoza/qgis-server
Then I connect to the container (docker exec -it qgis_server bash) and install the programs I will need to install qgis-atlasprint: apt-get install vim unzip wget -y >/dev/null.
Now I install qgis-atlasprint following the documentation: wget "https://github.com/3liz/qgis-atlasprint/archive/master.zip" && unzip master.zip && mv qgis-atlasprint-master atlastprint && rm master.zip && service apache2 reload.
Now I try to generate a PDF accessing to the following URL: http://localhost:8080/?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetPrintAtlas&TEMPLATE=Atlas&MAP=/dev/shm/myproject/myproject.qgs&FORMAT=pdf&DPI=300&EXP_FILTER=93
And the result page is a 500 Internal Server Error and here is the log I can see in /tmp/qgis_server.log:

Actually it doesn't seem to be a parse problem as I tried to avoid warnings following this commit on another project and now I don't have the warning anymore, don't have any more logs but still have the error 500.

for elem in tree.findall('.//Composer[@title="%s"]' % composer_name):Do you know where I could find some more complete logs to track down this problem?
Do you still have this issue?
Do you migrate to QGIS 3.4?

I finally used QGIS running in a bash script rather than qgis-server: https://gis.stackexchange.com/a/289645/73088 & https://gis.stackexchange.com/a/289122/73088 (so perhaps this issue is still happening).
You error is about Composer which has been removed in QGIS 3.0. It is now Layout so it's a new XML structure. The code has changed also in this area of the code. Let's close this issue, feel free to reopen a ticket if you have another error.
