Hello,
I have the following problem:
I configured orthanc.json to load the Worklist plugin.
"Plugins" : [
"/usr/local/share/orthanc/plugins/libModalityWorklists.so"
],
"Worklists" : {
"Enable": true,
"Database": "/home/k002941/WorklistsDatabase"
},
"DicomModalities" : {
"findscu" : ["FINDSCU", "127.0.0.1", 1234],
"modality" : ["MODALITY", "10.0.0.6", 104]
},
I put a worklist file into the specified folder.
But when I do a query I get the following error:
findscu -v -W -k "ScheduledProcedureStepSequence[0].Modality=CT" 127.0.0.1 4244

Thanks! The trace file had the solution in it. There was a problem with the directory with the worklist in it. I changed it and now it is working fine.
Below you can see the trace logfile.
