Error while deploying and testing Lambda function

Can you help I have a lambda function with name insertaurora.ts

and i am calling the lambda as below

 const insertaurora = new lambda.Function(this,'LambdaHandler',{
      runtime : lambda.Runtime.NODEJS_16_X,
      code : lambda.Code.fromAsset(path.join(__dirname, '/../lambda/')),
      handler : 'insertaurora.handler'
    });

Following is my tsconfig

{
  "compilerOptions": {
    "target": "es2020",
    "strict": true,
    "preserveConstEnums": true,
    "noEmit": true,
    "sourceMap": false,

  },
  "exclude": ["node_modules", "**/*.test.ts"]
}

  }
}

When i try to deploy and test i am getting the following error

"errorType": "Runtime.ImportModuleError", "errorMessage": "Error: Cannot find module 'insertaurora'\nRequire stack:\n- /var/runtime/index.mjs", "trace": [ "Runtime.ImportModuleError: Error: Cannot find module 'insertaurora'", "Require stack:", "- /var/runtime/index.mjs", " at _loadUserApp (file:///var/runtime/index.mjs:951:17)", " at async Object.UserFunction.js.module.exports.load (file:///var/runtime/index.mjs:976:21)", " at async start (file:///var/runtime/index.mjs:1137:23)", " at async file:///var/runtime/index.mjs:1143:1" ]

Can you help?

Also do we have any sample that connects to lambda via apigateway and the lambda should be connecting to aurora to insert data

lambda should be a typescript file with .ts extension
