ePub	Page ? Chapter 6 - related to confirmed serious technical error additional change needed	Chapter 6. Section: Adding the Custom Logic for Resizing the Image As per https://sharp.pixelplumbing.com/install#aws-lambda - nodejs runtime must be 12.x. I got an error with the default of 10.x "Something went wrong installing the "sharp" module" need to update \lambda-trigger-example\amplify\backend\function\<S3Trigger>\<s3trigger>-cloudformation-template.json line 59 from "Runtime": "nodejs10.x", to "Runtime": "nodejs12.x", Note from the Author or Editor: I've just made these updates to the most recent version in the OReilly portal, but for anyone that is running into this, here is what needs to be fixed: Sharp requires version 12.x of Node.js so we'll need to check the Lambda runtime in our function to be sure it's set to at least 12.x and if it is not, update it. To do this, open amplify/backend/function/<function-name>/<function-name-template>.json and be sure the "Runtime" property is set to at least nodejs12.x and if it is not, update and save the file: "Runtime": "nodejs12.x",	Anonymous	Sep 05, 2020
