@dhirajkhodade My issue was due to the default codebuild image using npm v6.x instead of npm v7.x, which i’m using locally and which produces a lockfileVersion:2 instead of lockfileVersion:1 package-lock.json file. So when codebuild pulls the code from my repo, it’s getting a package-lock.json that isn’t compatible with npm v6.x but it tries to use it anyway without throwing a mismatch error.

Potential solutions:

• Down grade npm locally to v6.x., then rm -rf package-lock.json && npm i to generate and commit a lockfileVersion:1 lock file
• Create/use an image that has npm v7.x and point the environment build image to your image repository like so:

         synthAction: SimpleSynthAction.standardNpmSynth({
           ...
           environment: {
             buildImage: codebuild.LinuxBuildImage.fromEcrRepository(...),
           },
         })
