Error when creating a connection via SDK

[vladfeigin]

Hi,

I'm following this document: https://microsoft.github.io/promptflow/how-to-guides/manage-connections.html
for a connection creation with SDK
When running this code:

from promptflow.client import PFClient
from promptflow.entities import AzureOpenAIConnection, CustomConnection

# Get a pf client to manage connections
pf = PFClient()

# Initialize an AzureOpenAIConnection object
connection = AzureOpenAIConnection(
    name="my_azure_open_ai_connection", 
    api_key="<your-api-key>", 
    api_base="<your-endpoint>",
    api_version="2023-03-15-preview"
)

# Create the connection, note that api_key will be scrubbed in the returned result
result = pf.connections.create_or_update(connection)

The error is thrown:
AttributeError: 'PFClient' object has no attribute 'connections'

My prompt flow version is : 1.15.0

Thanks,
