CloudCode Task Timeout

I’m running a task that is loading data from another database JA DB and it’s timing out. How can I keep the task from restarting?

You can add the following to your task to catch timeouts and high memory usage.

export async function run(event) {

    this.on('beforeTimeout', () => {
        // The task is about to timeout, just return.
        // You can also report errors to log services
        return;
    });
    this.on('highMemory', () => {
        // The task is reaching the memory threshold, just return.
        // You can also report errors to log services
        return;
    });

}

If the beforeTimeout or highMemory events trigger, one should consider changing the task or enqueue another task to continue.

Hi @mike_barnes. I am trying to test if this works, but I am not able to trigger the beforeTimeout function using a while loop. My CloudCode task is version 1.11.0

export async function run() {
    this.on('beforeTimeout', () => {
        const _timeout_error = `${this.name} - Script timeout imminent!`;
        console.log(_timeout_error);
        return;
    });

   while (true) {
    }

}

I still automatically retries the task. My goal is to prevent the automatic retry.

@david - Adding a timeout to your while loop with something like this should work, waiting for 50ms in each iteration:

while(true) {
    await new Promise(resolve => setTimeout(resolve, 50));
}

If you have asynchronous operations in the while loop, then the beforeTimeout function should be triggered without requiring the above timeout.
