- Start Syncope with docker compose or in embedded mode. Ensure that Activiti workflow is enabled.
- On Google Chrome (the error happens on version 74.0.3729.169) go to Configuration -> Workflow. Click on User Workflow and than on workflow modeler.
- You'll see a popup page containing html definition of model.html page, i.e. the page is not rendered.
The same procedure on Firefox 67.0 works and the modeler is correctly rendered.
