## Bug Report

AWS Landing Zone version 2.4.1 is currently broken. More specifically, validation of manifest.yaml has been broken since Dec 30 when version 1.8.0 of https://pypi.org/project/pykwalify was released. This release requires schemas to be written in YAML 1.2. However, Landing Zone's current [schema](https://s3.amazonaws.com/solutions-reference/aws-landing-zone/latest/aws-landing-zone-validation.zip) and manifest file adhere to YAML 1.1 (where `Yes|yes` still means `true`). The result is that the Build step of AWS-Landing-Zone-CodePipeline currently fails during schema validation.

## Hotfix

Update the buildspec of AWS-Landing-Zone-CodeBuild like this:

```diff
-      - pip install --upgrade pykwalify
+      - pip install --upgrade pykwalify==1.7.0 # HOTFIX for schema validation
```

AWS should apply that fix to the initiation template or, better yet, update all affected files to YAML 1.2.
