使用Restful API 调用 GPT-4 with vision 时，提示 "Backend returned unexpected response. Please contact Microsoft for help."，如何修复？

Question

在japan east区域创建的计算机视觉增强和gpt-4，参考 “Use Vision enhancement with video”教程，地址是：https://learn.microsoft.com/en-us/azure/ai-services/openai/how-to/gpt-with-vision?tabs=rest%2Csystem-assigned%2Cresource#use-vision-enhancement-with-video

Create Index 和 Create Ingestion 都成功了，“Integrate your video index with GPT-4 Turbo with Vision”时发生异常，响应结果：{"error":{"code":"InternalServerError","message":"Backend returned unexpected response. Please contact Microsoft for help."}}，没有其它信息可以参考。请告诉我如何继续定位问题或者如何解决这个问题？
