使用Bref Lambda自定义运行时和AWS CDK时出错libncurses.so.6

Question

我正在尝试使用AWS CDK而不是无服务器在AWS Lambda中使用Bref自定义运行时。

CDK代码如下所示。

const region = cdk.Stack.of(this).region;
    //arn:aws:lambda:ap-southeast-1:209497400698:layer:php-74:18
    const brefLayerVersion = `arn:aws:lambda:${region}:209497400698:layer:php-80:8`;
    const assetPath = path.join(__dirname, '../../lambda');
    const asset = lambda.Code.fromAsset(assetPath);
    
    const lambdaFunc = new lambda.Function(this, 'LambdaFunction', {
      runtime: lambda.Runtime.PROVIDED,
      handler: 'src/index.php',
      layers: [
        lambda.LayerVersion.fromLayerVersionArn(this, 'BrefPHPLayer', brefLayerVersion),
      ],
      code: asset,
    });
    
    new cdk.CfnOutput(this, 'LambdaFunctionArn', { value: lambdaFunc.functionArn });

这里是完整的源代码https://github.com/petrabarus/cdk-bref-function

当我尝试使用AWS CLIAWS lambda invoke-function-name arn:blabla手动调用时，它显示错误。

Cloudwatch日志显示了如下内容。

/opt/bin/php: error while loading shared libraries: libncurses.so.6: cannot open shared object file: No such file or directory

如果我将部署与无服务器框架进行比较，那么配置（层、代码等）几乎是相同的。我错过了什么？

Bref1.0需要提供AmazonLinux2运行时。这是更新的CDK代码。

    const lambdaFunc = new lambda.Function(this, 'LambdaFunction', {
      runtime: lambda.Runtime.PROVIDED_AL2,
      handler: 'src/index.php',
      layers: [
        lambda.LayerVersion.fromLayerVersionArn(this, 'BrefPHPLayer', brefLayerVersion),
      ],
      code: asset,
    });
