yaml: line 2: did not find expected key: what it means and how to fix it
Fix "yaml: line 2: did not find expected key": Go/Kubernetes YAML error. What it means and the fastest fixes (indentation, tabs, lists) without uploading data.
did not find expected key (YAML)
Troubleshoot did not find expected key (YAML) with a stable workflow: validate YAML, fix the minimal block, and re-validate before conversion (no upload).
TL;DR: Validate locally, pinpoint the failing spot, apply the minimal fix, then validate again.
Fast no-upload workflow
- Validate the input (strict rules, correct encoding, correct delimiter/quotes).
- Locate the exact position/line reported by the parser or validator.
- Fix the smallest broken part (often a quote, escape, delimiter, or a truncated copy/paste).
- Re-validate and only then convert/export.
