    Hi Sandeep,
     
    Can you tell us what Dynamics 365 application this question is related to? There are several different solutions in the Dynamics 365 family, like: Sales, Finance, Supply Chain Management, Project Operations, and Business Central. If you can clarify the product, we can move the question to the dedicated forum for that solution.

    Not a ton of information to go off here, so not sure if we can help too much.  I would imagine you just need to add a null check into your JavaScript.
     
    if (abc != null) {
    **Do something
    }
