weiqingy opened a new issue, #2413:
URL: https://github.com/apache/auron/issues/2413
**Describe the bug**
The Pull Request Labeler workflow (the `triage` check) fails on PRs whose
run happens after #2410 was merged, with:
```
##[error]YAMLException: deficient indentation (27:7)
```
while parsing `.github/labeler.yml`. This blocks the `triage` check on
affected PRs (for example #2409).
**Root cause**
#2410 bumped `actions/labeler` from v6 to v7. labeler v7 depends on
`js-yaml` `^5.1.0`, which is stricter about indentation of multi-line flow
sequences than the version v6 used. The current `.github/labeler.yml` writes
each label's globs as a multi-line flow sequence:
```yaml
infra:
- changed-files:
- any-glob-to-any-file: [
".github/**",
".gitmodules"
]
```
js-yaml 5.x rejects the closing-bracket indentation here. This is
reproducible locally: `js-yaml` 5.2.1 (the version labeler v7 resolves) throws
the exact `deficient indentation (27:7)` on the current file, while `js-yaml`
4.3.0 parses it without complaint.
**To Reproduce**
1. Open or re-run any PR after #2410 merged.
2. The `Pull Request Labeler / triage` check fails in a few seconds.
**Expected behavior**
The `triage` check passes and labels are applied.
**Additional context**
Fix: write the glob lists as block sequences (the style `actions/labeler`
documents for v5+), which parses cleanly under js-yaml 5.x. This is the same
class of change as #1842, which adapted the config for the v4 to v6 bump.
