```

### Expected behavior

Successful builds

### Reproduction steps

This occurs only on a single backend environment (production). As far as I know, there is no different between any of the environments, but I'm also unsure how to troubleshoot this more.

### Build Settings

```yaml
version: 1
backend:
phases:
build:
commands:
- '# Execute Amplify CLI with the helper script'
- amplifyPush --simple
frontend:
phases:
preBuild:
commands:
- yarn install
build:
commands:
- yarn run build
artifacts:
baseDirectory: build
files:
- '**/*'
cache:
paths:
- node_modules/**/*
```

### Additional information

https://github.com/aws-amplify/amplify-console/issues/1787
https://github.com/aws-amplify/amplify-console/issues/1784
https://github.com/aws-amplify/amplify-console/issues/1298

All of these issues suggest changing the version of the CLI. I've tried with the following versions [from this page](https://www.npmjs.com/package/@aws-amplify/cli/v/6.3.0-beta.0) with no success:
```
6.2.1
6.1.1
5.6.0
5.5.0
5.3.0
5.0.1
4.52.0
```

Start with the build settings and the amplifyPush --simple entry point, then inspect the build log around initialization of the production backend environment. Compare the production environment with the working environments and review related issues 1787, 1784, and 1298; done means the backend build completes successfully.
