AWS Lambda - Timeout

Question

I have a simple lambda function which calculates a result asynchronously. I can log the result and it seems to be correct but for some reason the lambda function doesn't return successfully, like I am getting a timeout. If you look at the timestamps you can see that the result is calculated way before the timeout. The weird thing is that it works fine when I am using axios but whenever I use fauna it doesn't work anymore, but it does log the correct result... I have been sitting on this problem for days and have no clue what to do. I am using the serverless framework along with this template .

Response
{
  "errorMessage": "2021-03-10T07:11:11.567Z 0180b87e-e01f-4527-8c7e-4c1dd5e3e354 Task timed out after 6.01 seconds"
}

Any help would be much appreciated!

Found the issue. Within the handler I set the context.callbackWaitsForEmptyEventLoop = false. Alternatively when using middy you can use this middleware
