Steps to fix it: -

1. Download your project(function) form AWS Lambda using Action->Export function and unzip it.

2. Install Latest version of node in your local system(say node 8.10.0). You can see i already have 8.10.0.

3. Go to your unzipped project folder via terminal and type

   npm rebuild

4. After this again zip this project and uplaod it on AWS Lambda and select the node runtime one you updated with (suppose it is node 8.10.0 then select runtime in aws lambda function runtime as node 8.10x).

Hope it helps.

Thanks
