由于错误而导致部署失败 属性变量的值必须是具有字符串（或简单类型）属性的对象

Question

我收到如下无服务器错误： 发生错误：CandidateSubmissionLambdaFunction - 属性变量的值必须是具有字符串（或简单类型）属性的对象。

我尝试将值从 yml 文件更改为字符串，然后我也遇到了同样的错误。

我的 Yml 文件代码如下：

frameworkVersion: ">=1.1.0 <2.0.0"

provider:
  name: aws
  runtime: nodejs8.10
  stage: dev
  region: us-east-1
  environment:
    CANDIDATE_TABLE: ${self:service}-${opt:stage, self:provider.stage}
    CANDIDATE_EMAIL_TABLE: "candidate-email-${opt:stage, self:provider.stage}"
    iamRoleStatements:

        Action:
          - dynamodb:Query
          - dynamodb:Scan
          - dynamodb:GetItem
          - dynamodb:PutItem
        Resource: "*"

        StreamSpecification:
          StreamViewType: "NEW_AND_OLD_IMAGES"
        TableName: ${self:provider.environment.CANDIDATE_TABLE}

functions:
  candidateSubmission:
    handler: api/candidate.submit
    memorySize: 128
    description: Submit candidate information and starts interview process.
    events:
      - http:
          path: candidates
          method: post 

环境信息

     OS:   linux
     Node Version:  8.10.0
     Serverless Version: 1.27.3

我想在 aws 上部署它并想执行 curd 操作。

您的 YAML 配置中用于 value 的变量之一可能是错误的类型。

${self:service} 未在 YAML 中定义，但在中被引用

provider:
  environment:
    CANDIDATE_TABLE: ${self:service}-${opt:stage, self:provider.stage}
