Hey. I try to create a KB through API, nothing crazy just some texts.
I get this error:

```500 - "{\"status\":\"error\",\"message\":\"Internal Server Error\"}"```

I tried to send sample payload:
```
{
  "knowledge_base_name": "Sample KB",
  "knowledge_base_texts": [
    {
      "text": "Hello, how are you?",
      "title": "Sample Question"
    }
  ]
}
```

I saw that the SDK might work, but i need my backend to do processing of the data before so I prefer to use HTTP requests.

Hey <@689561551853584518> 

A 500 Internal Server Error is typically caused by a request formatting or header issue rather than the content itself.

You can verify few things like 
Knowledge Base via HTTP:
The request includes Content-Type: application/json

Authorization header is set as Bearer <API_KEY>
The request uses POST and the correct Knowledge Base creation endpoint

knowledge_base_texts is a non-empty array and each item contains a valid text field string

If the same payload works with the SDK but fails over HTTP, the issue is usually related to headers, authorization, or JSON encoding.

I checked all of that
Headers are ok and used like with any other http request i used until now
The content-type is also set.
I used a lot of http requests until now and didn't have a problem, that is the first one i encountered a problem with.

Ok I report the issue as soon get a reply I will reach out to you

ensure you have the right link
