Description

In the page https://docs.cypress.io/guides/continuous-integration/aws-codebuild

The guide to run in codebuild is

phases:
  install:
    # ...
  build:
    commands:
      - npm start:ci &
      - npx cypress run --record --parallel --browser $CY_BROWSER --ci-build-id
        $CODEBUILD_INITIATOR --group "$CY_GROUP" --spec "$CY_SPEC" --config
        "$CY_CONFIG"

However it won't work if the codebuild is running in a pipeline, because the CODEBUILD_INITIATOR will become the codepipeline's id.

Suggest to change the variable to CODEBUILD_BUILD_ID.
