Google cloud platform Google Vision OCR多文本检测

我正在尝试使用谷歌云视觉进行多语言文本检测。但我有个问题。 如果我将请求文本检测api端点发送到此url

https://vision.googleapis.com/v1/images:annotate?key=XxxXX

以及这个机构

{
  "requests": [
    {
      "image": {
        "source": {
          "imageUri": "image_url"
        }
      },
      "features": [
        {
          "type": "DOCUMENT_TEXT_DETECTION",
          "maxResults": 1
        }
      ],
      "ImageContext": {
        "languageHints": [
          "tr", "en"
        ]
      }
    }
  ]
}

我得到了这个错误代码

{
"error": {
    "code": 400,
    "message": "Invalid JSON payload received. Unknown name \"image_context\" at 'requests[0]': Cannot find field.",
    "status": "INVALID_ARGUMENT",
    "details": [
        {
            "@type": "type.googleapis.com/google.rpc.BadRequest",
            "fieldViolations": [
                {
                    "field": "requests[0]",
                    "description": "Invalid JSON payload received. Unknown name \"image_context\" at 'requests[0]': Cannot find field."
                }
            ]
        }
    ]
}

}

什么是问题？

问题是字段

“ImageContext”

，应该是

“ImageContext”

，小写为“i”。
