Thanks Thomas for detailed explanation.

I have generated dummy worklist files using the python script below. I have started the server and when I query it is returning empty response.

I have attached logs as well.

mwl script: https://github.com/ChillarAnand/RIS-Bridge/blob/master/mwl.py
starting server: $ wlmscpfs --data-files-path mwl 8042 --no-fail --debug
request: $ findscu 0.0.0.0 8042 -W -k QueryRetrieveLevel=PATIENT -k PatientName='*' --call test -d
log: https://gist.github.com/ChillarAnand/86378a73cf1e64e16a3e23916066a1c6

QueryRetrieveLevel (0008,0052) is not an allowed attribute for the Modality Worklist C-FIND Information model. I suspect that this is causing the problem.

See PS3.4, K.6-1
