[Bug]: N8n/API Service is busy, please try again later.

Current Behavior

Trying to access the API using API key, but getting response 5000 - Oops! Service is busy, please try again later. This all started from trying to connect to Lowcoder from N8n using the community node, but cannot see any apps in the list, all the while receiving a successfully connected authentication test.

I've made sure I have a published app in my workspace, but can't seem to get the list to display. Also tried to manually access an app via ID, but N8N doesn't do anything.

Please advise!

Expected Behavior

Connect to API using Bearer token and n8n node using email/password.

Steps to reproduce

1. Set up n8n community node and add authentication.

2. Try to select an app from list.

3. Connect to API at https://my-domain.com/api/users/me using Bearer token

This behaviour appears likely because we have made improvements and made changes in the app list API. We need to look into the n8n Plugin and excuse for this problem! In the meantime you can still make use of n8n in the expected way - but would just copy the APP ID "per hand" in the dialogue.
