New Feature

Description:

Context: We want to retrieve conversations that were created via another service. In that service, when the API is called, the "input_file" values are transmitted in base64.

When I try to list items for a conversation, I encounter an error:

In InputMessageContentInputFile.php line 42:

  Warning: Undefined array key "file_data"

By another service you mean not-OpenAI? The nulling of more fields will probably fail since tests expect those non-null, but I enabled build for you to see that.

It goes through the OpenAI API but via a python script. Here is an example:

python
response = client.responses.create(
        model=model,
        input=[
            {
                "role": "user",
                "content": [
                    {
                        "type": "input_file",
                        "filename": "tuto_mapping.pdf",
                        "file_data": f"data:application/pdf;base64,{tuto_mapping_base64_string}",
                    },
                    {
                        "type": "input_file",
                        "filename": "document.pdf",
                        "file_data": f"data:application/pdf;base64,{document_base64_string}",
                    },
                    {
                        "type": "input_text",
                        "text": "xxxxxx",
                    },
                ],
            },
        ],
        conversation=conversation_id # conv_691c21b669b48190af42f85a3...
    )

Thank you for enabling the tests, I will adapt them. @iBotPeaches

Could you add 2 tests for the old form (string) and new (missing or null).

Sorry that a base test doesn't exist for ContentInputFile, but looking at this directory you should see its pretty simple to do
