Error stack:

FetchError: request to [https://https//bbb-328x3047.weaviate.network/v1/schema](https://https//bbb-328x3047.weaviate.network/v1/schema) failed, reason: getaddrinfo EAI\_AGAIN https

errno: ‘EAI\_AGAIN’,  
code: ‘EAI\_AGAIN’  
}

This is the only code I have.

const client = weaviate.client({  
scheme: “https”,  
host: “[https://bbb-328x3047.weaviate.network](https://bbb-328x3047.weaviate.network)”,  
apiKey: “API KEY”  
});

```
const className = 'Question';
const classObj = {
    class: className,
    vectorizer: 'text2vec-openai',
};

let result = await client.schema.classCreator().withClass(classObj).do();

console.log(JSON.stringify(result, null, 2));

```

The step generating the error is the let result line. The client variable seems to be holding the db object.

I’m new to weaviate. If anyone has a working example of Javascript code with a connection to the database, adding a schema, and doing a simple search that would be great.

Thanks

Hi! Welcome to our community 🤗

The issue here is that you are providing the schema together with the hostname.

Try this:

```auto
const client = weaviate.client({
scheme: “https”,
host: “bbb-328x3047.weaviate.network”,
apiKey: “API KEY”
});

```

Let me know if this helps 🙂
