Hi Vinay!
As of the release of AWS Authentication v3.0.0 you can add a BasicClientConfig object and adjust timeout settings (or an endpoint) in there. You can read more about this in this blogpost also:

Let me know if it helped!
Hi Vinay, I found a section in the Mendix documentation about the lambda connector. In the last paragraph an invocation type is mentioned which allows you to run asynchronously. Maybe this will help to avoid the time out?
