Null Value error on DF field read

We have integrated Entity of DS into studio and when we are reading any null value for field then this throw error as Object reference not found. But if we have value then its working good.

Is it a bug?


It is an expected behavious that when something is null then ideally we would get an object reference not set error…May be you can use IsNothing(value) to check if there is a value before trying to use it or convert it to .ToString


@Arvind_Kumar1 can you please post a screenshot of the workflow so that I can better assist on whether or not it is an expected behavior?
