Index.list error

As explained here Manage RAG documents, I defined an ID prefixes rule to reference parent documents. Now i want to list all vectors based on prefix with this script

for ids in index.list(prefix=‘doc1#’, namespace=‘ns1’):

Unfortunately when i run this code I get this error: ‘Index’ object has no attribute ‘list’.
How can I solve this problem?

HI @damiano.tedoldi, are you using a serverless index? Please note that the list operation is supported only for serverless indexes.

If you are using a serverless index, please share how you are connecting to the index. For example, you may be using index = pc.Index("<index_name>").

Hi Zeke,

thanks for your reply. Yes, I’m using a serverless index.
For connecting to the index I use index = pc.Index(“<index_name>”) .

@damiano.tedoldi Please ensure you are using v3.1.0 of the pinecone-python-client. Only this most recent version supports the list operation.
