Conf.Language(26)

Error message

Conf.Language(26)

What it means

Loading a snapshot document version requires the repository encryption key (Conf.Repo.Key) to be present, since snapshots are stored encrypted. If no repo key is configured (key length < 1), the kernel returns localized message key 26, which tells the user to set the repo key / passphrase first.

Solutions

1. Generate or enter the repo encryption key in Settings - About (or via the repo key API), then retry
2. Check len(Conf.Repo.Key) before requesting snapshot versions
3. Ensure i18n key 26 exists in all language files if localizing

Example fix

// before
loadDocVersion(fileID) // no repo key configured
// after
// set Conf.Repo.Key via the kernel repo-key API first, then:
loadDocVersion(fileID)

if (!window.siyuan.config.repo.key) { showToast(i18n[26]); openRepoKeyDialog(); }

const hasRepoKey = (conf: IConfig) => typeof conf.repo?.key === "string" && conf.repo.key.length > 0;

try { await api.loadDocVersion(fileID); } catch (e) { if (String(e) === i18n[26]) { await promptForRepoKey(); retry(); } }

When it happens

Trigger: Calling loadDocVersion for a snapshot version when no sync/repo passphrase has ever been generated or entered in this workspace.

Common situations: Fresh workspace without encryption key setup; accessing history before configuring cloud sync and its passphrase; Conf not yet initialized with Repo.Key.
