App worked on VSCode but didn’t after deployed to Lambda, no error in CloudWatch

I have this piece of code that runs perfectly fine locally.

But after I deployed it to AWS Lambda, it didn’t execute as expected, plus, it did not print any errors to CloudWatch for me to see what had happened.

I assume that it was because of the async/await that caused it but it seems to be correct.

Did anyone witness it before?

module.exports.fetch = async event => {
  const getParametersResponse = await ssm.getParameters({
    Names: [
      "TOKEN",
      "ACCESS_KEY"
    ]
  })

  await axios
    .get(url)
    .then(async (res) => {
      return downloadFile(res.data, project)
    })
    .then(async () => {
      const readStream = await zipFile.openReadStream(entry)
      return sendToDrive(readStream, project, gdriveKey)
    })
    .catch((error) => {
      console.log("error")
    })
};

It looks like your function has a timeout set to a too-small value. By default, the timeout is set to 3 seconds, and if I’m not mistaken that’s what can be seen in the logs you’ve pasted. Increase the timeout and the function should be able to execute.
