如何自动禁用路径和资产的AWS元数据？

Question

有3种类型的元数据CDK正在写入CFN。版本、路径和资产。有关于如何禁用版本元数据的文档，它运行得很好，但我正在努力解决其余的问题。CLI选项--路径元数据错误--资产元数据错误工作得很好，但是有点烦人。

我已经看过CDK源代码，试图找出插入cdk.json的关键词，但是它们被忽略了。下面是详细的cdk输出，它读取我的设置，似乎忽略了我关心的2。

cdk.json: {
  "app": "python app.py",
  "versionReporting": false,              <-- custom, works as intended
  "assetMetadata": false,                 <-- custom, doesn't seem to do anything
  "pathMetadata": false,                  <-- custom, doesn't seem to do anything
  "context": {
    "@aws-cdk/aws-apigateway:usagePlanKeyOrderInsensitiveId": true,
    "@aws-cdk/core:stackRelativeExports": "true",
    "@aws-cdk/aws-rds:lowercaseDbIdentifier": true,
    "@aws-cdk/aws-lambda:recognizeVersionProps": true,
    "@aws-cdk/core:bootstrapQualifier": "myQualifier",
    "aws:cdk:enable-path-metadata": false, <-- custom, produces namespace warnings
    "aws:cdk:enable-asset-metadata": false, <-- custom, produces namespace warnings

  }
}
merged settings: {                        <------------results of combined settings
  versionReporting: false,                <-- worked
  pathMetadata: true,                     <--didn't work
  output: 'cdk.out',
  app: 'python app.py',
  assetMetadata: true,                    <--didn't work
  context: {
    '@aws-cdk/aws-apigateway:usagePlanKeyOrderInsensitiveId': true,
    '@aws-cdk/core:stackRelativeExports': 'true',
    '@aws-cdk/aws-rds:lowercaseDbIdentifier': true,
    '@aws-cdk/aws-lambda:recognizeVersionProps': true,
    '@aws-cdk/core:bootstrapQualifier': 'myQualifier',
    'aws:cdk:enable-path-metadata': false, <-- seems like a dud
    'aws:cdk:enable-asset-metadata': false,<-- seems like a dud
  },
  debug: false,
  profile: 'mycdkIAMUser',
  toolkitBucket: {},
  staging: true,
  bundlingStacks: [ 'my-cdk-policies' ],
  lookups: true
}

从CDK源代码来看，似乎CLI选项是目前唯一可行的选项。

看看execProgram()第23至31行

const pathMetadata: boolean = config.settings.get(['pathMetadata']) ?? true;
if (pathMetadata) {
  context[cxapi.PATH_METADATA_ENABLE_CONTEXT] = true;
}

const assetMetadata: boolean = config.settings.get(['assetMetadata']) ?? true;
if (assetMetadata) {
  context[cxapi.ASSET_RESOURCE_METADATA_ENABLED_CONTEXT] = true;
}

CLI选项都默认为true，然后覆盖它们各自的上下文变量。可能是错误报告的罪证。
