perform null check in Dataweave
isEmpty is a dataweave core function that can be used to perform null check In Mule 4.
It works on Array,String and Object and gives the result accordingly
Examples:
%dw 2.0 output application/json --- [isEmpty([]), isEmpty([123]) ]
Result
[True,false]
Examples:
%dw 2.0
output application/json
---
[ isEmpty(""), isEmpty("string") ]
Result
[True,false]
isEmpty(object)
it will return true if the object is empty else false
Example:
%dw 2.0
output application/json
---
isEmpty({})
Result
true

Does this work to check date value also? I need to update Salesforce date value from Mule. If you date is empty it should overwrite date field in Salesforce with Null, otherwise with actual value.
