The input “Records” must not be null or empty.

All the process variables currently contain null values:

• pv!currentCase
• pv!redeemedLoans
• pv!amortization

We are using the following expression to exclude null values:

reject( a!isNullOrEmpty(_), { pv!currentCase, pv!redeemedLoans, pv!amortization } )

However, when all process variables are null, the expression returns an empty list, which causes the error.
 

The input “Records” must not be null or empty.

Is there an alternative way to configure the XOR gateway that it skips the write operation when all values are null?, since i dont want to increase number of node by adding xor gate ?
