Resource contains a duplicate storage key: ${resource.id}

Error message

Resource contains a duplicate storage key: ${resource.id}

What it means

Thrown when a single resource's originalStorageKeys array contains the same key more than once. originalStorageKeys lists where the resource bytes live in storage; intra-resource duplicates imply a packing bug.

Solutions

1. Dedupe originalStorageKeys within each resource before validation.
2. Re-export the resource.
3. Audit the exporter's key-collection loop.

Example fix

// before
validateBackupManifestGraph(manifest)

// after
for (const r of manifest.resources) {
  r.originalStorageKeys = [...new Set(r.originalStorageKeys)]
}

function resourcesHaveUniqueStorageKeysLocally(manifest: BackupManifest): boolean {
  return manifest.resources.every((r) => new Set(r.originalStorageKeys).size === r.originalStorageKeys.length)
}

try {
  validateBackupManifestGraph(manifest)
} catch (error) {
  if (/duplicate storage key/.test((error as Error).message)) dedupeLocalStorageKeys(manifest)
  throw error
}

When it happens

Trigger: resource.originalStorageKeys has a repeated string within one resource entry.

Common situations: Exporter appended the same storage key twice; hand-edited manifest; naive concatenation of key lists.
