Failed to process ${failures.length} blobs:

Error message

Failed to process ${failures.length} blobs:

What it means

Warning logged in `exportDocs` when one or more blobs could not be written into the export zip — readFromBlob threw (missing/corrupt blob) or the blob entry was absent. The failing blob ids are listed and export continues with everything else, producing a zip that omits the failed assets.

Solutions

1. Inspect the listed blob failures and retry the zip transform.
2. Remove or replace the failing blobs.

When it happens

Trigger: Triggered when exporting docs to a zip archive and one or more blobs fail to be retrieved from the blob storage, so the export proceeds with those blobs missing.

Common situations: Occurs when exporting a workspace whose attachments are not fully synced or were removed. Re-export after sync completes, and expect missing files in the archive otherwise.
