NetSuite Admin Tip | Understanding "RangeError: Maximum Call Stack Size Exceeded" in SuiteScript

The error "RangeError: Maximum call stack size exceeded" occurs when a function recursively calls itself without a proper stopping condition, eventually consuming all available memory space to track the repeated calls. This error is often associated with recursion—when a function calls itself to perform repetitive tasks. Without an effective way to stop these calls, the call stack overflows, resulting in this error.

In NetSuite, this occurs when the call stack—i.e., the internal record of function calls made by JavaScript during the execution of code—reaches its maximum size limit.

This typically happens when:

• Excessive Recursion: A function calls itself (either directly or indirectly) too many times without hitting a base case (e.g., a recursive function doesn't break properly).
