我尝试使用CDK在AWS的Amplify中部署next.js（ssr）应用程序，但Amplify无法将应用程序识别为next.js ssr。但当我使用AWS UI手动部署时，应用程序被识别为SSR，并按预期工作。
x1c 0d1x这是由aws-cdk/aws-amplify v118生成的，如下所示：

import * as cdk from '@aws-cdk/core';
import * as amplify from '@aws-cdk/aws-amplify';
import codebuild = require('@aws-cdk/aws-codebuild');

export class AmplifyStack extends cdk.Stack {
    constructor(scope: cdk.Construct, id: string, props: cdk.StackProps) {
        super(scope, id, props);

        const sourceCodeProvider = new amplify.GitHubSourceCodeProvider({
            owner: '.....',
            repository: '....',
            oauthToken: cdk.SecretValue.secretsManager('github-token'),

        });
        const buildSpec = codebuild.BuildSpec.fromObjectToYaml(
            {
                version: 1,
                applications: [
                    {
                        frontend: {
                            phases: {
                                preBuild: {
                                    commands: [
                                        "npm install"
                                    ]
                                },
                                build: {
                                    commands: [
                                        "npm run build"
                                    ]
                                }
                            },
                            artifacts: {
                                baseDirectory: ".next",
                                files: [
                                    "**/*"
                                ]
                            },
                            cache: {
                                paths: [
                                    "node_modules/**/*"
                                ]
                            }
                        }
                    }
                ]
            }
        );
        const amplifyApp = new amplify.App(this, "cdk-nf-web-app", {
            sourceCodeProvider: sourceCodeProvider,
            buildSpec: buildSpec
        });

        amplifyApp.addBranch('develop', {
            basicAuth: amplify.BasicAuth.fromGeneratedPassword('dev')
        });
        amplifyApp.addCustomRule({
            source: "</^[^.]+$|\\.(?!(css|gif|ico|jpg|js|png|txt|svg|woff|ttf|map|json)$)([^.]+$)/>",
            target: "/index.html",
            status: amplify.RedirectStatus.REWRITE
        });
    }
}

这是相同什么AWS已生成当我从UI手动。这里的区别是缺乏框架标识如图所示。有什么想法？
