The server cannot start with the datastore for Azure CosmosDB vCore provider

[adgrajales1]

Hello,

When I execute with the Azure CosmosDB datastore provider, the server is not able to start as it's trying to create the provider without providing the num_lists and similarity params to the factory

Steps to reproduce:

• docker build -t chatgpt-retrieval-plugin .
• docker run -it --env DATASTORE=azurecosmosdb --env BEARER_TOKEN="<some_token>" --env OPEN_API_KEY="<some_api_key>" --env AZCOSMOS_API=mongo-vcore --env AZCOSMOS_CONNSTR="<some_connection_string>" --env AZCOSMOS_DATABASE_NAME=<some_database> --env AZCOSMOS_CONTAINER_NAME=<some_collection> chatgpt-retrieval-plugin

Result:

INFO:     Waiting for application startup.
ERROR:    Traceback (most recent call last):
  File "/usr/local/lib/python3.10/site-packages/starlette/routing.py", line 671, in lifespan

    datastore = await get_datastore()
  File "/code/./datastore/factory.py", line 42, in get_datastore
    return await AzureCosmosDBDataStore.create()
TypeError: AzureCosmosDBDataStore.create() missing 2 required positional arguments: 'num_lists' and 'similarity'

ERROR: Application startup failed. Exiting.

Expected result:

• The server starts successfully
