I migrated a custom plugin that using with Umbraco 7 to 8 recently, In Umbraco 8.0.0 and Umbraco 8.1.0, It works fine. But when I try that plugin with Umbraco 8.14.1 issue is occurring.

Basically, the plugin is a media picker, after adding content to the grid editor I can select my plugin and add media to the grid Until click save or save and published which is working as expected. However, after clicking save or save and publish page is reloading and added content is missing. I can't see any error on the log file. Does anybody have an idea how to sort out his issue?
