Bug Description

n8n version: 2.21.6 and 2.21.7 (confirmed on both) Deployment: Self-hosted Docker, Community Edition Browser: Chrome 148, Edge (both affected)

Description

Opening the credential creation form for any OAuth2-based credential type freezes the browser tab permanently. The form never loads. Simple API key credential types (e.g. Slack API) are unaffected.

Console error

GET https://<host>/rest/external-secrets/secrets 404 (Not Found) @ utils2.mjs:74 @ externalSecrets.ee.store.ts:121 @ externalSecrets.ee.store.ts:173 @ externalSecrets.ee.store.ts:209 @ CredentialEdit.vue:454 (Promise.then) @ ui.store.ts:527 @ Modal.vue:121 @ CredentialsSelectModal.vue:51

Root cause

CredentialEdit.vue calls externalSecrets.ee.store during initialization, which fetches /rest/external-secrets/secrets. This endpoint does not exist on Community Edition (returns 404). The promise in the store never resolves or rejects on a 404 response, permanently blocking CredentialEdit.vue:454 and preventing the credential form from rendering.

To Reproduce

1. Self-hosted n8n Community Edition via Docker
2. Navigate to Credentials → New Credential
3. Select any Google OAuth2 credential type (e.g. Google Sheets OAuth2 API)
4. Browser tab freezes — form never loads

No workaround found. Intercepting the endpoint at the proxy level to return {"data":{}} does not resolve the freeze, suggesting the unhandled promise rejection occurs before or independently of the response body.

Expected behavior

Community Edition should handle the missing EE endpoint gracefully — treat the response as an empty secrets list — and allow the credential creation form to load normally.
