Sora 2 video create fails with bad request

[artemptushkin]

Given:

@SpringBootTest
@ActiveProfiles("integration-test")
class SoraStrategyTest {
    val path = Path("/my/path/bear.jpeg")

    @Autowired
    lateinit var openAiClient: OpenAIClient

    @Test
    fun testIt() {
        val prompt = "bear is cooking a fish"
        openAiClient.videos().create(
            VideoCreateParams.builder()
                .model(VideoModel.SORA_2)
                .prompt(prompt)
                .seconds(VideoSeconds.of("4"))
                .let { builder ->
                    path.let {
                        builder
                            .inputReference(MultipartField.builder<InputStream>()
                                .value(it.inputStream())
                                .contentType("image/jpeg")
                                .build())
                    }
                }
                .size(VideoSize._720X1280)
                .build()
        )
    }
}

It fails with

com.openai.errors.BadRequestException: 400: Invalid type for 'input_reference': expected a file, but got a string instead.

I tried many options... need a clue please

It works like this in raw

@Test
    fun testRaw() {
        val prompt = "bear is cooking a fish"

        val r = generateVideo(prompt, path.inputStream())
        println(r.code)
        println(r.body?.string())
    }

    fun generateVideo(prompt: String, imageStream: InputStream): Response {
        val client = OkHttpClient()

        val body = MultipartBody.Builder()
            .setType(MultipartBody.FORM)
            .addFormDataPart("prompt", prompt)
            .addFormDataPart("model", "sora-2")
            .addFormDataPart("size", "720x1280")
            .addFormDataPart(
                "input_reference",
                "image.jpg",
                RequestBody.create("image/jpeg".toMediaTypeOrNull()!!, imageStream.readBytes())
            )
            .build()

        val request = Request.Builder()
            .url("https://api.openai.com/v1/videos")
            .post(body)
            .addHeader("Authorization", "Bearer ...")
            .build()

        return client.newCall(request).execute()
    }

I think the API is expecting a filename maybe... In your first code example you're not passing one while in your second one you are passing image.jpg

@TomerAberbach, you are right, thank you.. I think I didn't try with the file name that day
