Orthanc version for using ModalityWorklists plugin


I’m trying to use Orthanc with the ModalityWorklists plugin. I compiled the plugin with success and added the following to configuration.json:

“Plugins” : [

I get the following error when running orthanc:

It seems to be a problem with my version of Orthanc core, which is 1.3.1 but I cannot find any 1.3.2 version here https://www.orthanc-server.com/download.php or on bitbucket. Does anyone know how solve this?

Thank you in advance for your help.



You have visibly compiled the ModalityWorklists plugin in the “default” (aka. mainline) branch of the source repository of Orthanc. You have therefore obtained a cutting-edge release of the plugin that is not compatible with the latest 1.3.1 release of Orthanc.

Hello Sebastien,

It worked perfectly, thanks!
