I have an Initiator task, assosiated to a Human Task which points to an external UI. Mostly, it works as expected (the link appears on the workspace, under "Applications", I can click it and it instantiates correctly, and this task on the workspace redirects to external URI.
The unexpected behaviour occurs in between, when I Click on the Application Link, and it shows a popup redirecting to a "404 - Not found", but when I click on the instance created in the workspace, the external UI works fine.
