如何摆脱无服务器“警告：在根目录遇到无效配置：无法识别的属性'deploymentBucket'”

Question

我有一个在无服务器框架版本 3.7.5 上运行的 Web 应用程序。每次我部署我的 lambda 函数时，我都会收到以下警告：

“警告：在根目录遇到无效配置：无法识别的属性 'deploymentBucket'”。

我已附上下面的“serverless.yml”文件以供外部审查。我对“deploymentBucket”属性的配置是否无效？我需要更改或编辑任何属性吗？

注意：部署工作正常，因为它只是一个警告，我可以继续测试我的 api 端点......我只是觉得这个警告有点麻烦，想一劳永逸地删除它。提前致谢！

这是我的 serverless.yml 文件

# Welcome to Serverless!
#
# This file is the main config file for your service.
# It's very minimal at this point and uses default values.
# You can always add more config options for more control.
# We've included some commented out config examples here.
# Just uncomment any of them to get that config option.
#
# For full config options, check the docs:
#    docs.serverless.com

# Happy Coding!

Answer 1

警告意味着 deploymentBucket 属性未被识别，因此它没有做你认为应该做的事情。

根据serverless docs，deploymentBucket 应该是provider 下的属性而不是根属性。

Answer 2

我可以通过将deploymentBucket 属性移动到provider 下而不是将其注册为根属性来消除此警告。下面附上修改后的 serverless.yml 文件：

service: poppy-seed

provider:
  name: aws
  runtime: java11
  timeout: 30
  lambdaHashingVersion: 20201221 
  deploymentBucket:
    blockPublicAccess: true 
    skipPolicySetup: false 
    name: poppy-seed
    maxPreviousDeploymentArtifacts: 5
    versioning: false # enable bucket versioning. Default is false


package:
  artifact: build/libs/poppy-seed-dev-all.jar

functions:
  poppy-seed:
    handler: com.serverless.lambda.Handler


events:
  - http:
      path: "{proxy+}"
      method: ANY
      cors: true

plugins:
  - serverless-sam
