# X_STORAGE_SCAN_UNAVAILABLE

## Means

the upload scanner could not give a verdict

## Typical cause

the uploadScanner installed in runtime.ts rejected (daemon down, timeout, file past its limit), or the per-attempt copy could not be read for it, and the upload policy fails closed; the attempt copy is deleted and the upload stays pending

## Fix

`promoteAttachment({ disk, key, orgId, target, policy })   # again once the scanner answers — or uploadPolicy({ onScanUnavailable: 'accept' }) to promote unscanned files`
