Hi everyone,
Recently I have this problem with IG.
When created in modal dialog page, IG JS API not working.
When calling this:
var widget =apex.region("IG_DATA").widget();
This error occurred in browser console :
VM4334:1 Uncaught TypeError: Cannot read properties of null (reading 'widget')
This problem does not happen in Normal Page or Non-Modal dialog Page.
Please help.
