[Bug] delete_all index is not working. about pinecone-python-client HOT 3 OPEN

Note that delete(delete_all=True only deletes the vectors in the specified namespace (defaults to the default namespace). Indeed, I see the expected behaviour when I have two namespaces - default and ns_2 and call delete(delete_all=True):

>>> import pinecone
>>> pinecone.__version__
'3.0.2'
>>> pc = pinecone.Pinecone(api_key=my_api_key)
>>> index = pc.Index(host=my_index)
>>> index.describe_index_stats()
{'dimension': 4,
 'index_fullness': 0.0,
 'namespaces': {'': {'vector_count': 2}, 'ns_2': {'vector_count': 2}},
 'total_vector_count': 4}
>>> index.delete(delete_all=True)
{}
>>> index.describe_index_stats()
{'dimension': 4,
 'index_fullness': 0.0,
 'namespaces': {'ns_2': {'vector_count': 2}},
 'total_vector_count': 2}

Could you confirm what namespace(s) your data is stored in?

from pinecone-python-client.

currently, I only use the default namespace so I guess there is no need to pass the namespace.

See I run this cell and it respond with empty {}.

but in pinecode dashboard vectors are still present.

Today I got a new error, namespace is not found. namespace parameter is optional for the default namespace.
I'm getting the same error in the curl request too.
