Sharp on AWS Amplify Backend Lambda Causing Build to Fail

Question

I am pretty new to aws amplify and have an amplify app that has a backend lambda function which uses sharp as a dependency. When I push to git to trigger a deploy, my build is failing I think due to vips/vips8 a sharp dependency not being found.

Relevant log

Running amplify push from my windows box packages up the lambda and deploys it working totally fine, the problem is only when it pulls from github and tries to run through the amplify build platform. I am running node v 16

Thanks for any ideas! My google-foo is failing me this time.

According to the installation guide for AWS Lambda you can add the following command as the preinstall script to the package.json of your Amplify lambda:

{
  "name": "file-storage-get-s3-signed-link",
  "version": "1.0.0",
  "main": "index.js",
  "scripts": {
    "preinstall": "SHARP_IGNORE_GLOBAL_LIBVIPS=1 npm install --arch=x64 --platform=linux --libc=glibc sharp"
  }
}
