Function node did not timeout under certain situation

[justin0108]

Hi,

The function node is suppose to timeout and throw interrupted after 5 seconds. However this does not always happen. I have created 2 examples to illustrate it. I purposely use "while (true)" just to simulate that it has a bunch of unoptimised code.

This will throw Error: interrupted

export const handler = async (input) => {
  let i = 0;
  while (true) {
    ++i;
  }
  return input;
};

This does not seem to throw any error after a long time ( > 5 seconds )

export const handler = async (input) => {
  while (true) {
    console.log("hello")
  }
  return input;
};

We have another situation where it is not "while (true)" but its a bunch of heavy looping codes. It is not optimised. We are expecting the function to throw interuppted but it didnt which causes the whole flow to "hang" indefinitely.
