What causes "Backup selection not found in plan: {planId}" in floci-io/floci?

Use ListBackupSelections on the plan to get IDs guaranteed to match, then retry with that plan/selection pair

ResourceNotFoundException

ResourceNotFoundException

Error message

Backup selection not found in plan: {planId}

What it means

Thrown by getBackupSelection when the selection exists in the store but belongs to a different plan than the one in the request. AWS Backup scopes selections under their plan ARN, so a plan/selection mismatch is reported as ResourceNotFoundException (HTTP 404) — the pair simply does not exist together.

Solutions

Use ListBackupSelections on the plan to get IDs guaranteed to match, then retry with that plan/selection pair
Verify both identifiers came from the same creation flow — regenerate them if unsure

Defensive patterns

Strategy: validation

Validate before calling

boolean pairExists = backup.listBackupSelections(ListBackupSelectionsRequest.builder()
    .backupPlanId(planId).build()).backupSelectionsList().stream()
    .anyMatch(s -> selectionId.equals(s.selectionId()));
if (!pairExists) throw new NoSuchResourceException(planId + "/" + selectionId);

Try / catch

catch (ResourceNotFoundException e) { re-enumerate selections under the plan and correct the stale id; }

Prevention

Always obtain selection IDs from ListBackupSelections of the same plan
Never pair a selection ID from one fixture with a plan ID from another

When it happens

Trigger: Calling GetBackupSelection (or DeleteBackupSelection, which delegates to it) with a selectionId that exists but whose BackupPlanId differs from the requested planId.

Common situations: Copy-pasting IDs between test fixtures so selection and plan ids cross wires; enumerating all selections globally and calling them against the wrong plan; truncation or typo in one of the two identifiers.
