Amplify Hosting feature

Build settings, Frontend builds

Is your feature request related to a problem? Please describe:

I am having a use-case of developing several NextJS applications (SSG) and deploying them to AWS Amplify. I am using AWS amplify hosting, where directly linking each GitHub repository to amplify apps. And configuring YAML file for frontend deployment. All applications are deployed and working fine.

Problem statement: Now I need to setup a quality gate in the deployment process, Where I have to check certain parameters (Package version of few NPM modules) before deployment.

I am trying to implement this with command hooks. Officially its mentioned pre and post push hooks will get triggered by default in amplify hosting.

I have added amplify/hooks folder.

When I tried to trigger a build, these hook scripts are not getting executed. Is it applicable only for backend execution?

Is there any other better way to handle this use-case with AWS amplify CICD for SSG deployments?

Describe how you'd like this feature to work

Currently I am trying with cURL to pass the data to an API.

version: 1
frontend:
phases:
preBuild:
commands:
- NEXT_VERSION=$(node -p -e "require('./package.json').dependencies.next")
- REACT_VERSION=$(node -p -e "require('./package.json').dependencies.react")
- echo $NEXT_VERSION
- echo $REACT_VERSION
- RES=$(curl -s -X POST -H "Content-type: application/json" -d {"next":"1.00","react":"1.1.0"} [endpoint])
- echo $RES
- npm ci
build:
commands:
- rm -rf .next
- npm run build
artifacts:
baseDirectory: .next/
files:
- '/*'
cache:
paths:
- node_modules//*

But receiving an error as

[ERROR]: !!! CustomerError: The commands provided in the buildspec are malformed. Please ensure that you have properly escaped reserved YAML characters. If you have a ':' character in your command, encapsulate the command within quotes.

But while executing the same buildspec without assigning the curl response to a variable its executing properly.

Is there any easy way to post required info to external APIs via hooks in frontend deployment.
