Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🔵 Low · up to The PR restores consistent handling of image-pull failures and cleans up lint issues, but the restart workflow still converts unexpected lookup failures into a misleading no-job result, which can prevent a restart from completing. The change is mergeable with explicit owner awareness or follow-up to narrow the exception handling. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Handle a missing pod and narrow the exception handling.
get_job_latest_pod returns None when no pod exists, so pod.status raises AttributeError outside this handler. except Exception also converts API, authentication, response-parsing, and programming errors into a logged return. Handle pod is None explicitly, catch only a documented expected exception, and propagate unexpected failures with their traceback.

Summary
Main fix —
playbooks/robusta_playbooks/image_pull_backoff_enricher.py: the file importsget_image_pull_backoff_container_statusesfromrobusta.core.playbooks.pod_utils.imagepull_utilsand then immediately shadows it with a local copy (ruff F811). The two are not equivalent:waiting.reason in ["ImagePullBackOff", "ErrImagePull"]waiting.reason == "ImagePullBackOff"Because the local def wins, the reporter silently ignores pods in
ErrImagePull— whileget_image_pull_backoff_enrichment(called right after) uses the shared, broader logic. Removing the stale copy restores the imported implementation and makes reporter + enricher consistent. Also removed the imports (enum,Flag,List,ContainerStatus,PodStatus) that are unused once the duplicate is gone.Also included:
src/robusta/api/__init__.py—ResourceAttributeswas listed twice in the same import block (F811); removed the duplicate.playbooks/robusta_playbooks/job_restart_on_oomkilled_community.py— bareexcept:→except Exception:andstatus.state.running == None→is None(E722/E711).Testing
