Requested ID already exists

I am trying to create a blog application using react as frontend and appwrite as backend service. I can add or create one post but when i try to add second post i got error

appwrite.js?v=ccfb24fa:850 Uncaught (in promise) AppwriteException: Document with the requested ID already exists. Try again with a different ID or use ID.unique() to generate a unique ID. at Client. I have tried using ID.unique() but got the same error. Can anyone please help me solve this issue.

TL;DR

Developers are passing slug as ID, causing the error "Document with the requested ID already exists." Suggestion to post a picture of the document in the Appwrite console. Further info needed: Appwrite version and SDK version. The error can be resolved by generating a unique ID using ID.unique() or manually ensuring unique IDs when creating posts in the blog application.
