Troubleshooting
Connection test fails
Section titled “Connection test fails”- Confirm Supabase URL uses
httporhttps. - Confirm anon/publishable key is used (not service role key).
- Confirm setup SQL has been run successfully.
SQLite data seems missing
Section titled “SQLite data seems missing”- In browser/PWA mode, SQLite data is stored per browser/app install. Switching browsers, clearing site data, or using a different profile will not show the same local vault.
- In Electron, confirm you are opening the same configured SQLite file path if you chose a custom file-backed database.
- If no SQLite path/name was set, Keyper uses its default local database for that runtime.
New credential types fail (document / misc)
Section titled “New credential types fail (document / misc)”- Run
migration-add-document-misc-types.sqlon existing databases. - Verify the
credentials_credential_type_checkconstraint includesdocumentandmisc. - Re-test create/edit after migration.
Vault unlock fails
Section titled “Vault unlock fails”- On Supabase, confirm you are signed in to the intended account. Signing out and back in is how you switch.
- On SQLite or Neon, confirm the username on the unlock screen matches the vault you want.
- Confirm a
vault_configrow exists for that owner and has awrapped_dekvalue. - If Keyper shows the upgrade screen instead, the database still needs the 1.3.0 migration. See Upgrading to 1.3.0.
Sign-up fails
Section titled “Sign-up fails”- “Sign-ups are disabled on this Supabase project” means the Email provider is off. Enable it under Authentication → Providers.
- On SQLite or Neon, a vault is created the first time you unlock with a new username.
- Confirm username format: 3-50 chars, letters/numbers/hyphen/underscore.
- Confirm passphrase is at least 8 characters and matches confirmation.
- If registration started from User Management, allow the lock-screen reload and complete creation there.
User switching appears stuck
Section titled “User switching appears stuck”- User switching performs a context reset + reload to avoid cross-user cryptographic state.
- After switch, unlock using the target user’s passphrase.
- Use Refresh Users in User Management if a newly created user does not appear immediately.
Decryption or reveal issues
Section titled “Decryption or reveal issues”- Ensure vault is unlocked before revealing secrets.
- Confirm
secret_blobexists and is valid JSON object with expected fields. - Inspect browser console for
CryptoErrorcontext.
UI inconsistencies
Section titled “UI inconsistencies”Some docs and components in repo represent older flows. If behavior differs, treat active code path in SelfHostedDashboard + dashboard modals as authoritative.
Document preview behavior
Section titled “Document preview behavior”- Inline preview currently appears only for text-like files (
text/*,.txt,.md). - Binary uploads (for example
.pdf,.doc,.docx,.odt) are download-only by design in current release.
