Question

当我尝试使用授权者调用lambda函数时，出现“ AuthorizerConfigurationException”错误。主要功能创建为：

functions:
  sftpDir:
    handler: handler.sftp_dir
    events:
      - http:
          path: sftp/dir
          method: get
          cors:
            origins:
              - '*'
            headers:
              - Content-Type
              - X-Amz-Date
              - Authorization
              - X-Api-Key
              - X-Amz-Security-Token
            allowCredentials: true
          authorizer:
            arn: arn:aws:lambda:us-east-1:xxxxxxxxxxxx:function:authorize-jwt-dev-authorizerJwt
            resultTtlInSeconds: 0
            identitySource: method.request.header.Authorization
            identityValidationExpression: .*

当我在生成的授权者上的apigateway控制台中运行测试时，我得到：

但是，实际上响应中的JSON是有效的。用jq进行解析可以得出：

{
  "context": {
    "user_id": 3,
    "permissions": [
      "Manager",
      "MFI Distribution Survey",
      "Money Fund Intelligence",
      "Money Fund Wisdom",
      "MFI Daily Data",
      "Consulting Services",
      "MFI Custom Reports",
      "Money Fund Intelligence XLS",
      "Crane Corporate",
      "Crane Web Access",
      "Crane Index"
    ],
    "iat": 1534769754,
    "exp": 1534773354
  },
  "policyDocument": {
    "Version": "2012-10-17",
    "Statement": [
      {
        "Action": "execute-api:Invoke",
        "Effect": "Allow",
        "Resource": "arn:aws:execute-api:us-east-1:xxxxxxxxxxxx:yyyyyyyyyy/null/GET/"
      }
    ]
  }
}

policyDocument中的“ null”看起来可疑，但它肯定是好的json。该资源来自eventMethodARN-因此大概只是直接调用它的产物。（我也尝试返回一个字符串化的结果，无济于事。）

有什么建议吗？

更新我从示例中注意到，我应该将响应包装在字典中，并将其主体化为{"statusCode": 200, "body": <response above, stringified>}。

错误是相同的。
