InvalidObjectState
AWS InvalidObjectState means the requested operation is not valid for the object’s current state in S3 (HTTP 403).

What Does Invalid Object State Mean?
The object exists but is not currently operable for the requested action, so reads/copies/mutations fail until lifecycle, restore, or lock prerequisites are satisfied.
Common Causes
- -Object is in a storage class or lifecycle state that does not allow the requested operation.
- -Archived object has not been restored before read/copy request.
- -Retention/legal-hold constraints block mutation or deletion path.
- -Operation assumes immediate availability after lifecycle transition.
How to Fix Invalid Object State
- 1Inspect object storage class, restore status, and lock metadata before retrying.
- 2Restore archived objects and wait for restore completion where required.
- 3Use operation paths compatible with retention and legal-hold constraints.
- 4Retry only after object-state prerequisites are satisfied.
Step-by-Step Diagnosis for Invalid Object State
- 1Use HeadObject to inspect storage class, restore, and lock state fields.
- 2Correlate lifecycle policy actions with failure timestamps.
- 3Validate permissions and governance settings for the requested operation.
- 4Re-test after explicit state transition completion.
Object Lifecycle and Restore Validation
- -Inspect HeadObject lifecycle attributes before operation dispatch (example: Glacier/Deep Archive object still shows restore in-progress).
- -Correlate lifecycle transitions with failure timing (example: object moved by lifecycle rule before downstream job attempted immediate read).
Retention and Governance State Checks
- -Audit Object Lock and legal hold constraints for mutate/delete paths (example: governance-mode retention blocks overwrite until retain-until date).
- -Verify operation-specific prerequisites rather than blind retries (example: retrying GetObject on non-restored archive never succeeds until restore completes).
How to Verify the Fix
- -Re-run operation and confirm InvalidObjectState is cleared.
- -Validate object metadata reflects expected availability/state.
- -Ensure dependent workflows no longer fail on object-state checks.
How to Prevent Recurrence
- -Add object-state preflight checks before read/copy/delete paths.
- -Monitor restore backlog and lifecycle transitions continuously.
- -Document operation compatibility per storage class in runbooks.
Pro Tip
- -route archive-tier objects through a restore-orchestration queue and release consumers only after HeadObject restore state confirms temporary availability.
