Amazon web services boto3 AWS MediaConvert未知“；“图像插入器”；参数

我按照aws示例配置在MediaConvert中创建作业模板，作业如下：

{
 ...
 "Inputs": [
      {
        "AudioSelectors": {
          "Audio Selector 1": {
            "Offset": 0,
            "DefaultSelection": "DEFAULT",
            "ProgramSelection": 1
          }
        },
        "VideoSelector": {
          "ColorSpace": "FOLLOW"
        },
        "FilterEnable": "AUTO",
        "PsiControl": "USE_PSI",
        "FilterStrength": 0,
        "DeblockFilter": "DISABLED",
        "DenoiseFilter": "DISABLED",
        "TimecodeSource": "EMBEDDED",
        "FileInput": "s3://rodeolabz-us-west-2/vodconsole/VANLIFE.m2ts",
        "ImageInserter": {
          "InsertableImages": [
            {
              "Opacity": 50,
              "ImageInserterInput": "IMAGE_URL",
              "Layer": 0,
              "ImageX": 0,
              "ImageY": 100,
              "Width": 242,
              "Height": 97
            }
          ]
        }
      }
}

但在运行作业时，我收到如下错误：

{
 ...
 "Inputs": [
      {
        "AudioSelectors": {
          "Audio Selector 1": {
            "Offset": 0,
            "DefaultSelection": "DEFAULT",
            "ProgramSelection": 1
          }
        },
        "VideoSelector": {
          "ColorSpace": "FOLLOW"
        },
        "FilterEnable": "AUTO",
        "PsiControl": "USE_PSI",
        "FilterStrength": 0,
        "DeblockFilter": "DISABLED",
        "DenoiseFilter": "DISABLED",
        "TimecodeSource": "EMBEDDED",
        "FileInput": "s3://rodeolabz-us-west-2/vodconsole/VANLIFE.m2ts",
        "ImageInserter": {
          "InsertableImages": [
            {
              "Opacity": 50,
              "ImageInserterInput": "IMAGE_URL",
              "Layer": 0,
              "ImageX": 0,
              "ImageY": 100,
              "Width": 242,
              "Height": 97
            }
          ]
        }
      }
}

设置中的未知参数。输入[0]：“ImageInserter”必须是以下选项之一：AudioSelector组、AudioSelector、CaptionSelector、DeblockFilter、DenoiseFilter、FileInput、FilterEnable、FilterStrength、InputClipping、ProgramNumber、PsiControl、TimecodeSource、VideoSelector
