DSAR-VB-1001: STORAGE_VERCEL_BLOB_FETCH_FAILED

Meaning

Fetching the binary payload of a Vercel Blob object failed after a successful HEAD request.

Probable Causes

• The blob URL returned by HEAD is no longer accessible.
• Network interruption between the backend and Vercel Blob storage.
• The blob was deleted or moved between the HEAD and GET requests.
• Vercel Blob returned a non-2xx HTTP status code.

How to Fix

1. Check error.details.httpStatus for the HTTP status code of the failed fetch.
2. Verify the blob exists in the Vercel Blob dashboard.
3. Confirm the BLOB_READ_WRITE_TOKEN is valid and has read permissions.
4. Retry if the failure is transient.

Retryable

Yes, when the cause is a transient network error. Persistent 4xx responses are not retryable.

Minimal Trigger Example

A getObject call where the blob URL returns a non-OK HTTP response.
