Issue
The upload field of a Liferay structure is in broken state when user performs any action.
Environment
Liferay DXP 7.4
Resolution
Structure with the "Upload" field is not working for the user.
Open the main menu on the top right -> Control Panel -> Configuration -> System Settings -> Module Container -> Component Blacklist.
We can observe "com.liferay.dynamic.data.mapping.internal.notification.DDMFormEmailNotificationSender" being blacklisted.
By clicking on the "Reset Default Values", or by removing "com.liferay.dynamic.data.mapping.internal.notification.DDMFormEmailNotificationSender" from "Blacklist Component Names
The user is able to use the "Upload" field without any further issue.
