Known Issues

Overview

This guide addresses a known issues in the Pepperi JS Client Side API Rule Engine.

---

Issue Description

• Problem: The Rule Engine currently does not support the Optional Chaining Operator (?.).

• Impact: Using this operator, such as x?.success, may cause errors in UDFs, stopping script execution.

• Recommendation: Avoid using the Optional Chaining Operator in Rule Engine scripts.

Incorrect Usage

let x = pepperi.api.userDefinedTables.getList({});
let data = x?.success ? x.objects : [];  // This will cause an error

Correct Workaround

let x = pepperi.api.userDefinedTables.getList({});
let data= x && x.success ? x.objects : []; // Safe alternative

• Explanation: The workaround uses a conditional check (x && x.success) to safely access x.objects, defaulting to an empty array the condition fails.
