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).
- Infinite Loops in Function Calls: Functions keep calling each other endlessly, leading to too many function calls stacking up.
- Large Arrays or Objects in Function Calls: Passing excessively large or deep objects as parameters between functions without breaking them down efficiently can also result in a full call stack.
To prevent or resolve this error:
- Check for Infinite Recursion: Make sure that any recursive functions have proper exit conditions or base cases that stop the recursion.
- Optimize Recursive Calls: Ensure that recursive functions aren’t consuming too much memory or causing unnecessary calls.
- Limit the Depth of Calls: If working with large data structures, consider breaking them into smaller, manageable chunks to avoid excessively deep call chains.
- Refactor to Avoid Circular Dependencies: If multiple functions are calling each other in a loop, refactor them to prevent the infinite calls.
