HR Case Creation page is not creating cases upon upgrading to London
Customized (hr_CoreUtils) Script Include.
This issue is caused due to customizations made to (hr_CoreUtils) Script Include below:
Since this Script Include has been modified, the necessary London updates were not applied upon upgrading. To resolve this issue please revert (hr_CoreUtils) Script Include above to the latest London version.
It is important to note that Script Includes which have been modified in prior releases may/may not have received the necessary London. Best Practice would be upgrading the customized script includes to the latest London version and applying your customizations to the latest version available. This will ensure you do not run into any unexpected issues upon upgrading to London or a future release.
