When using IIS as a web server, it is observed that process modeler icons are missing/broken:
This can happen if the worker.list property is not correctly configured or if there is a missing worker in the workers.properties file of the IIS setup.
Ensure the workers.properties is correctly configured as per this documentation and that there are no missing workers.
This article applies to all versions of Appian using IIS as a web server.
