### Description

I’m encountering a persistent `UnexpectedStatusCodeError` when trying to create a collection in Weaviate:

“name”: “UnexpectedStatusCodeError”,  
“message”: “Collection may not have been created properly.! Unexpected status code: 422, with response body: {‘error’: [{‘message’: ‘class name Collection\_test\_test already exists’}]}”

This occurs even after attempting to delete the existing collection before recreating it.

### Server Setup Information

- Weaviate Server Version: `1.30.7`.
- Deployment Method: Docker Image
- Multi Node? - Running locally on my machine and Weaviate Cloud instance
- Client Language and Version: Python (v4 client)
- Multitenancy?: No

### Any additional Information

What I’ve Already Tried:

1. Tested with new collection names (same error occurs).
2. Upgraded Weaviate server from `1.29` to `1.30.7`.
3. Uninstalled and reinstalled the latest `weaviate-client` package.

Note:

Ensured logic deletes and recreates the collection:

if \_client.collections.exists(collection\_name):  
\_client.collections.delete(collection\_name)  
time.sleep(2)  
\_client.collections.create(collection\_name, …)  
else:  
\_client.collections.create(collection\_name, …)

The exact same logic \*\*worked fine until last Friday. Even if the collection name is entirely new and never used before, the error is still raised.

hi @Rupa !!

Welcome to our community 🤗

Do you see any error logs on server after you issue the delete collection command?

Thanks!
