In a MacOS device with CWA for Mac installed, when launching session, a dialog with message "There is no application set to open the URL receiver://.../Citrix/.../clientAssistant/getIcaFile/..." is always prompted. The dialog asks end user to "Search the App Store for an application that can open this document, or choose an existing application on your computer".
'WorkspaceHelper' component inside CWA for Mac fails to be invoked upon the session launch from web browser. It is triggered by a recent Storefront server certificate renew.
The issue has been addressed by cleaning up the web browser Internet cache and restarting the web browser.
The article describes an ICA session launch failure in a Mac device related with Storefront server certificate.
