Hi Justin Ebenezer,
Thanks for contacting Syncfusion Forums.
Query: “TreeGrid control v17.1.39, after production build - Cannot read property 'prototype' of undefined”
From your query we understand you are facing issue with Checkbox column in EJS TreeGrid. We created sample using your code example and we are not able to reproduce the error at our end. But the reported issue may occur when you have not properly injected the services / modules in appmodule or Provides. So kindly ensure that whether you have injected modules properly.
For your convenience we have prepared as sample using 17.1.39 version.
