Function Returns Response After 38 Seconds and Ignores the Timeout Settings

Hi,

I noticed that some of my users who use products depending on serverless functions are getting an error response after about 40 seconds, even though I set the timeout to the maximum value of 900 seconds.

However, I decided to create a dummy function that waits for 50 seconds and then returns a Hello World response. The result is that after about 40 seconds, it returns a 202 status code with the response body Response not yet ready.

How can I make the function wait until the real promise finishes and then return the result, or at least wait until the timeout that I set in the function settings?

The dummy function code:

async function main(args) {
    const wait = (ms) => new Promise(resolve => setTimeout(resolve, ms));
    await wait(50000);
    return {"body": "Hello World!"};
}

The timeout settings

The result of the execution of the function after about 40 seconds
