Php Android改造多部分请求协议异常

我想发表一篇文章，对SlimApi端点进行改造。但每次我提出请求时，我都会收到：

java.net.ProtocolException: expected 638 bytes but received 2048

我的界面看起来像这样

@Multipart
@PUT("pictures")
Call<JSONObject> putImages(@Header("authorization") String apiKey,
                          @Part("view_time") RequestBody viewtime,
                          @Part("receiver") RequestBody receiver,
                          @Part("picture\"; filename=\"fileUpload.jpg\" ") RequestBody fileToUpload);

apiKey是一个简单的字符串。所有路径都有效并经过双重检查。现在，当我启动一个请求时，我会得到以下StackTrace：

当我使用手动REST客户端时，服务器端PHP工作得非常好。我尝试了许多解决方案，但我不知道如何让它发挥作用
