Missing Key

Error message

Missing Key

What it means

Thrown by the PGP widget's decode flow when a fetched encrypted resource has byteLength === 0. It is a sentinel guard meaning the fetch succeeded but the source contained no data, so there is nothing to decrypt; the widget returns a Blob URL for the empty buffer instead of entering the decrypt modal.

Solutions

1. Verify the source URL points to a non-empty PGP-encrypted file and that the upload/write step actually persisted content
2. Fetch the resource manually (curl/wget) to confirm it returns bytes
3. Check that the storage backend is not returning empty bodies for missing or truncated files
4. Include the source URL in the error message to identify the empty resource
