‘cluster_url’ must be one of: [<class ‘str’>], but got <class ‘NoneType’>

what`s going on here? I got my cluster_url , but cannot use it

hi @bo_sun ! Welcome to our community :hugs:

Can you share some more code?

My bet is that if your are using a variable to define the cluster_url, it’s not working, as the client seems to be complaining that you passed a None value as the cluster_url, instead of a string.

Can you try replacing this variable with the actual value of the url, or print this cluster_url before passing it to the client?

Thanks!

hi @DudaNogueira print(type(APIKEY))

client = weaviate.connect_to_wcs(
    cluster_url=URL,
    auth_credentials=weaviate.auth.AuthApiKey(APIKEY)
    # headers={
    #     "X-OpenAI-Api-Key": os.environ["sk-xxx-xxxxx"]  # Replace with your inference API key
    # }
)

I used legitimate apikeys and url but it’s still showing the error

hi @VIVEK !! Welcome to our community :hugs:

Check your URL variable.

it is probably set to None instead of the value you want.

Hi @VIVEK,
You accidentally shared your API key, which I removed now, but you should probably cancel it and generate a new one.

The reason you are getting None is because you are passing the key into the os.environ() function call. This function is used to get the value of the provided environment variable. For example, you can add OPENAI_APIKEY =bla-bla-bla to your env variables, then when you call

os.environ("OPENAI_APIKEY")

You will get back “bla-bla-bla”

To solve this you have two options:

Option 1 - Add OPENAI_APIKEY env var

Add OPENAI_APIKEY to your environment variables, then connect to the client.

Note, the latest Weaviate client changed connect_to_wcs() to connect_to_weaviate_cloud()

client = weaviate.connect_to_weaviate_cloud(
    cluster_url=URL,
    auth_credentials=weaviate.auth.AuthApiKey(APIKEY)
    headers={
        “X-OpenAI-Api-Key”: os.environ["OPENAI_APIKEY"]
    }
)

Option 2 - provide the API key directly

Note, this approach is not safe if you plan to share your code, as you will expose your keys.

client = weaviate.connect_to_weaviate_cloud(
    cluster_url=URL,
    auth_credentials=weaviate.auth.AuthApiKey(APIKEY)
    headers={
        “X-OpenAI-Api-Key”: "your-api-key-goes-here"
    }
)
