Serverless部署AWS时Webpack无法解析模块问题求助

Context #

I'm building a backend using the Serverless Framework, basing my work on a demo API repository. I kept the core config and resource files the same, but adjusted my directory structure to place handlers at controllers/service/handler.js, and updated the function definitions in serverless.yml to:

functions:
  - ${file(routes/user/user.routes.definitions.yml)}

Here's the full content of my user.routes.definitions.yml:

healthcheck:
  # Defines an HTTP API endpoint that calls the healthcheck function in handler.js
  # - path: url path is /health-check
  # - method: GET request
  handler: handler.healthcheck
  events:
    - http:
        path: health-check
        method: get
        cors: true
create:
  handler: controllers/service/handler.main
  events:
    - http:
        path: users
        method: post
        cors: true
        authorizer: aws_iam
get:
  # Defines an HTTP API endpoint that calls the main function in get.js
  # - path: url path is /users/{id}
  # - method: GET request
  handler: controllers/service/handler.main
  events:
    - http:
        path: users/{id}
        method: get
        cors: true
        authorizer: aws_iam

The Problem #

When I run serverless deploy, I get consistent module-not-found errors for my dynamodb-lib and response-lib imports:

ERROR in ./controllers/user/get.js
Module not found: Error: Can't resolve '../../../libs/dynamodb-lib' in 'E:\work\dittytv\backend\controllers\user'
@ ./controllers/user/get.js 70:19-56

ERROR in ./controllers/user/list.js
Module not found: Error: Can't resolve '../../../libs/dynamodb-lib' in 'E:\work\dittytv\backend\controllers\user'
@ ./controllers/user/list.js 69:19-56

ERROR in ./controllers/user/create.js
Module not found: Error: Can't resolve '../../../libs/dynamodb-lib' in 'E:\work\dittytv\backend\controllers\user'
@ ./controllers/user/create.js 68:19-56

My controller files start with these import statements:

import * as dynamoDbLib from "../../../libs/dynamodb-lib";
import { success, failure } from "../../../libs/response-lib";

I've tried adjusting the paths to ./libs/, ./../../../libs, and other variations, but the error persists. I suspect the issue is with my Webpack configuration—here's what I'm using currently:

const slsw = require("serverless-webpack");
const nodeExternals = require("webpack-node-externals");

module.exports = {
  entry: slsw.lib.entries,
  target: "node",
  // Generate sourcemaps for proper error messages
  devtool: 'source-map',
  // Since 'aws-sdk' is not compatible with webpack,
  // we exclude all node dependencies
  externals: [nodeExternals()],
  mode: slsw.lib.webpack.isLocal ? "development" : "production",
  optimization: {
    // We no not want to minimize our code.
    minimize: false
  },
  performance: {
    // Turn off size warnings for entry points
    hints: false
  },
  // Run babel on all .js files and skip those in node_modules
  module: {
    rules: [
      {
        test: /\.js$/,
        loader: "babel-loader",
        include: __dirname,
        exclude: /node_modules/
      }
    ]
  }
};

Could someone help me figure out what's causing this and how to fix it?
