My nodejs app just printed out this error and crashed I am wondering what is the best solution to fix the issue?

    Does this answer your question? [Node.js heap out of memory](https://stackoverflow.com/questions/38558989/node-js-heap-out-of-memory) – Manuel Spigolon Nov 04 '20 at 13:50

    use `--max-old-space-size=SIZE` option argument by replace the size that you think is needed – Heartbit Nov 04 '20 at 13:58
  • You should first check what section of your program is eating up memory and does it need that much. If you don't think it should, then you should try to optimize your code otherwise go for custom heap size. – Pratyush Sharma Nov 04 '20 at 15:54

use set node_options=--max_old_space_size=SIZE and set SIZE as per your requirement
