无服务器框架：UpdateFunctionCode操作的请求必须小于69905067字节

Question

我正在使用包上传压缩文件

frameworkVersion: "=1.27.3"

service: recipes

provider:
  name: aws
  endpointType: REGIONAL
  runtime: python3.6
  stage: dev
  region: eu-central-1
  memorySize: 512
  deploymentBucket:
    name: dfki-meta
  versionFunctions: false
  stackTags:
    Project: DFKIAPP
  # Allows updates to all resources except deleting/replacing EC2 instances
  stackPolicy:
    - Effect: Allow
      Principal: "*"
      Action: "Update:*"
      Resource: "*"
    - Effect: Deny
      Principal: "*"
      Action:
        - Update: Replace
        - Update: Delete
      Resource: "*"
      Condition:
        StringEquals:
          ResourceType:
            - AWS::EC2::Instance
  # Access to RDS and S3 Bucket
  iamRoleStatements:
    -  Effect: "Allow"
       Action: "s3:ListBucket"
       Resource: "*"


package:
  individually: true

functions:
#  get_recipes:
#    handler: handler.get_recipes
#    module: recipes_crud
#    package:
#      individually: true
#    timeout: 30
#    events:
#      - http:
#          path: recipes
#          method: get
#          request:
#            parameters:
#              querystring:
#                persona: true

  get_recommendation:
    handler: handler.get_recommendation
    module: recipes_ml
    package:
      artifact: zipped_dir.zip
    timeout: 30
    events:
      - http:
          path: recipes/{id}
          method: get
          request:
            parameters:
              paths:
                id: true
              querystring:
                schaerfe_def: true
                saettig_def: true
                erfahrung_def: true
                schaerfe_wunsch: true
                saettig_wunsch: true
                erfahrung_wunsch: true
                gericht_wunsch: true
                stimmung_wunsch: true

无法理解此错误，不是69905067字节以下的52.18吗？

Answer 1

这似乎仅在使用无服务器上传单个 lambda 函数时才是一个问题，但如果您不提供 --function 参数并部署完整堆栈，那么它就可以正常工作！

Answer 2

根据文档https://docs.aws.amazon.com/lambda/latest/dg/limits.html，包大小应小于 50MB

来自这篇博文

增加的 20 MB 大概是为了解决与 AWS API 相关的请求开销（例如 zip 文件数据的 base64 编码）。到目前为止，50 MB 的限制是正确的。但是，我们还没有被打败。
