我在玩无服务器，我没有运气让serverless-offline与serverless-dynamodb-local一起工作。我有非常小的设置，它需要30分钟来重现，我这样做：
1.生成类似-sls create -t aws-nodejs-typescript --path folder-name的TS无服务器项目
1.安装依赖项npm i
1.添加DynamoDB本地npm install --save serverless-dynamodb-local
1.添加无服务器脱机npm install serverless-offline --save-dev
1.安装发电机b sls dynamodb install
现在我更新serverless.ts文件，如下所示
1.按正确顺序包括已安装的插件

plugins: [
    'serverless-esbuild',
    'serverless-dynamodb-local',
    'serverless-offline'
  ],

1.在custom中，添加DynamoDB配置，例如

custom: {
    esbuild: { ... },
    dynamodb: {
      stages: ['dev'],
      start: {
        migrate: true
      }
    }

1.最后一步是在资源中添加DynamoDB

resources: {
    Resources: {
      usersTable: {
        Type: 'AWS::DynamoDB::Table',
        Properties: {
          TableName: 'firstTable',
          AttributeDefinitions: [{
            AttributeName: 'id',
            AttributeType: 'S',
          }],
          KeySchema: [{
            AttributeName: 'id',
            KeyType: 'HASH'
          }],
          ProvisionedThroughput: {
            ReadCapacityUnits: 1,
            WriteCapacityUnits: 1
          }
        }
      }
    }
  }

**现在我尝试通过运行sls offline start -s dev来加速，但它抛出了下面的错误（执行不会停止）

(this如果从serverless.ts中删除migrate: true，则逻辑上不会引发错误）**

即使抛出错误，我仍然能够成功执行

> aws dynamodb list-tables --endpoint-url http://localhost:8000 --region localhost
{
    "TableNames": []
}

我没有改变任何其他代码比上述描述。我猜这将是一些非常基本的东西，像我错过了一些配置或东西的地方，但我找不到任何文件或其他职位，这将有助于。任何想法欢迎。
...由于我知道某些版本在过去遇到过问题，因此我使用的是package.json

"engines": {
    "node": ">=14.15.0"
  },
  "dependencies": {
    "@middy/core": "^2.5.3",
    "@middy/http-json-body-parser": "^2.5.3",
    "serverless-dynamodb-local": "^0.2.40"
  },
  "devDependencies": {
    "@serverless/typescript": "^3.0.0",
