Serverless离线启动时Schema重复类型错误的解决求助

大家好，我现在在部署一个基于NestJS的Serverless应用，运行sls offline start命令时遇到了Schema重复类型的错误。我尝试用npx serverless offline --allowCache命令来解决，但还是出现了右侧的错误（注：对应提问中提及的图片内容）。

下面是我的项目核心配置文件：

serverless.yaml配置 #

service: nest-serverless-lambda-demo

plugins:
- 'serverless-plugin-typescript'
- serverless-plugin-optimize
- serverless-offline

custom:
  serverless-offline:
    httpPort: 4000
    stageVariables:
      foo: "bar"
    allowCache: true

provider:
  name: aws
  runtime: nodejs12.x
  timeout: 100

functions:
  main: # The name of the lambda function
    # The module 'handler' is exported in the file 'src/lambda'
    handler: src/lambda.handler
    events:
    - http:
        method: ANY
        path: graphql

目前的困境是：执行sls offline start时触发了Schema重复类型的错误，查到资料说用npx serverless offline --allowCache可以解决，但运行该命令后还是遇到了错误。有没有大佬能帮忙分析一下问题出在哪，或者给个可行的解决办法？
