Google Drive object not found

Error message

Google Drive object not found: ${path}

What it means

Google Drive provider's get() resolves a path to a Drive object id via findObjectId; when no object matches the path it throws this not-found error. It indicates the backup file no longer exists at that path in the Drive account/folder.

Solutions

  1. Verify the file still exists in the Drive backup folder under the same account
  2. Call list() and match entries by path before get()
  3. Handle not-found as a stale manifest entry and offer re-upload/recreate

Example fix

// before
const buf = await store.get(entry.id)
// after
const entries = await store.list('')
if (!entries.some(e => e.path === entry.id)) throw new Error('stale entry')
const buf = await store.get(entry.id)
Defensive patterns

Strategy: validation

Validate before calling

const entries = await store.list('')
const exists = entries.some(e => e.path === entry.id)

Try / catch

try { await store.get(path) } catch (e) { if ((e as Error).message.includes('object not found')) return null; throw e }

Prevention

When it happens

Trigger: Calling store.get(path) for a backup path that was deleted in Google Drive, moved out of the backup folder, created under a different root folder, or when the OAuth user differs from the one who created the backup.

Common situations: User deleted the file in Drive manually; switching Google accounts; root folder cache pointing to another folder; restoring an old entry whose file was purged.

Understand the failure class

Background: 'Could not be found', 'does not exist', 'not found in database': the resource-not-found family when an ID, slug, key, or URI lookup comes back empty — this error's family across 20 libraries.
