I'm trying to create app with serverless framework.

Every functions works fine on my local machine.

But remote machine(Lambda) gives to below error message. (This take a 30sec)

 "message": "Endpoint request timed out"

Code size is 37.5 MB, and instance memory size is 3008 MB.

Any advice or suggestion would be appreciated. Thank you in advance

I solved my problems with set to callbackWaitsForEmptyEventLoop = false.

By default calling the callback() function in a NodeJS Lambda function does not end the function execution. It will continue running until the event loop is empty. A common issue with NodeJS Lambda functions continuing to run after callback is called occurs when you are holding on to open database connections. You haven't posted any code, so I can't give specific recommendations, but you would need to determine if you are leaving database connections open in your code or something similar.

Here's what the documentation says about the behavior of callbackWaitsForEmptyEventLoop:

callbackWaitsForEmptyEventLoop

The default value is true. This property is useful only to modify the
default behavior of the callback. By default, the callback will wait
until the Node.js runtime event loop is empty before freezing the
process and returning the results to the caller. You can set this
property to false to request AWS Lambda to freeze the process soon
after the callback is called, even if there are events in the event
loop. AWS Lambda will freeze the process, any state data and the
events in the Node.js event loop (any remaining events in the event
loop processed when the Lambda function is called next and if AWS
Lambda chooses to use the frozen process). For more information about
callback, see Using the Callback Parameter.
