Question

在运行cannot do operation on a non-existent table并尝试访问用户端点之后得到错误sls offline start。 serverless.yml文件如下：

service: 
  name: digital-secret

plugins:
  - serverless-dynamodb-local
  - serverless-offline # must be last in the list

custom:
  userTableName: 'users-table-${self:provider.stage}'
  dynamoDb:
    start:
      migrate: true

provider:
  name: aws
  runtime: nodejs8.10
  stage: dev
  region: us-east-2
  iamRoleStatements:
    - Effect: Allow
      Action:
        - 'dynamodb:Query'
        - 'dynamodb:Scan'
        - 'dynamodb:GetItem'
        - 'dynamodb:PutItem'
        - 'dynamodb:UpdateItem'
        - 'dynamodb:DeleteItem'
      Resource:
        - { "Fn::GetAtt": ["usersTable", "Arn"] }
  environment:
    USERS_TABLE: ${self:custom.userTableName}

functions:
  app:
    handler: index.handler
    events:
      - http: ANY /
      - http: 'ANY {proxy+}'
  user:
    handler: index.handler
    events:
      - http: 'GET /users/{proxy+}'
      - http: 'POST /users'

resources:
  Resources:
    usersTable:
      Type: 'AWS::DynamoDB::Table'
      Properties:
        TableName: ${self:custom.userTableName}
        AttributeDefinitions:
          - AttributeName: userId
            AttributeType: S
        KeySchema:
          - AttributeName: userId
            KeyType: HASH
        ProvisionedThroughput:
          ReadCapacityUnits: 1
          WriteCapacityUnits: 1

谁能帮忙指出这里出了什么问题？我浏览了文档，并在网上找到了许多不同的示例，但我看不出与上面的有所不同。

Answer 1

serverless-dynamodb-local文档说custom块的结构应如下：

custom:
  dynamodb:
    start:
      migrate: true

您有dynamoDb而不是dynamodb

Answer 2

如果其他人对此有疑问，我花了数小时试图找出问题所在，这是因为我无意中在serverless.yml中的[r] esources部分遇到了错误的情况

Resources:    <-- Needs to be lower case 'r'
  Resources:
    usersTable:
      Type: 'AWS::DynamoDB::Table'
      Properties:
  ...

未在serverless.yml文件中创建DynamoDB表
