In Axon Ivy 7.0 and earlier we used the ULC technology to build client-side UIs (Rich Dialogs). Our Admin UI was also built using this technology.
The client-side ULC libraries were signed using a code signing certificate expiring 2024-12-19.
Because the certificate uses "timestamping" your old Rich Dialogs and Admin UIs should still work for some years even with the expired certificate.
Because Axon Ivy 7.0 is out of support, we will not renew the certificate.
Please update to a newer version of Axon Ivy.
Also, you can sign the ULC libraries using your own code signing certificate. See https://dev.axonivy.com/doc/7.0/DesignerGuideHtml/ivy.concepts.html#ivy-extension-richdialog
