Hi ,
I am working with below dependencies in the React v15.5.4 project.
"@syncfusion/ej2-base": "^20.2.38",
"@syncfusion/ej2-dropdowns": "20.2.38",
"@syncfusion/ej2-react-popups": "20.2.38",
"@syncfusion/ej2-react-schedule": "20.2.38",
The code is working fine on my local but on pushing it to staging it loads the calendar view, but on trying to add an event it throws error like this =>

And i have no idea what is wrong, i am suspecting it might be related to some package function gone missing, So, any help on this is super helpful.
Thanks
