FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

This error message indicates that the JavaScript program has run out of memory and is unable to allocate any more memory for its processes. This can occur when a program is trying to process a large amount of data or when there is a memory leak in the program.

To resolve this issue, you can try the following:

1. Increase the heap memory limit using the --max-old-space-size flag. For example, node --max-old-space-size=4096 app.js.

2. Identify and fix any memory leaks in your code.

3. Optimize your code to use less memory. This can include optimizing data structures and algorithms, reducing unnecessary data processing, and minimizing the number of variables and objects in memory.

4. Consider using a tool like a memory profiler to track down memory leaks and other performance issues.

5. If all else fails, you may need to upgrade the hardware or use a cloud-based solution with more memory resources.
