Description

I have been trying to support PDF file processing with Claude, and I followed the description in the documentation, but the request directly times out.

This is the input I am testing against:

  {
    "role": "user",
    "content": [
      {
        "type": "text",
        "text": "What do you read?"
      },
      {
        "type": "file",
        "data": "https://<my_server_url>/files/68728cdeed4cdcfc8397a045",
        "mimeType": "application/pdf"
      }
    ]
  }

The same input and processing code has proper results from OpenAI and Google models. I have attempted using base64Url encoded string and it works on Anthropic provider, but strangely the url doesnt work, when the documentation for Anthropic stated directly it would work.
