YAML indent error fix for OpenAPI and configs
YAML is indentation-sensitive. Mixed spaces and tabs, or wrong nesting, breaks parsers used for OpenAPI and Kubernetes configs. Editors often hide the problem until deploy or codegen.
Common causes
- Tab characters mixed with spaces.
- Inconsistent indent level between siblings.
- Multi-line strings break alignment.
How to fix
- Paste the spec into OpenAPI Validator (JSON or YAML).
- Normalize indentation in the editor.
- Use a YAML-aware linter in CI.
