无服务器如果同一事件类型的前缀重叠，则两个规则中不能有重叠的后缀

Question

我正在尝试使用无服务器框架部署AWS Lambda，并在

serverless.yaml

中有以下内容

provider:
  name: aws
  runtime: python3.8
  region: us-west-2
  stackName: ${self:service}-${self:custom.name}-${opt:stage, 'dev'}
  stackTags:
    Service: "it"
  lambdaHashingVersion: 20201221
  memorySize: 128
  timeout: 900
  logRetentionInDays: 14
  disableDefaultOutputExportNames: true
  deploymentBucket: ${self:custom.deployment-s3-bucket}
  environment:
    S3_BUCKET: ${self:custom.bucket}
    S3_BUCKET_PATH_PREFIX: ${self:custom.path_prefix}
    REDSHIFT_DATABASE: ${self:custom.database}
    REDSHIFT_SCHEMA: ${self:custom.schema}
    REDSHIFT_TABEL_PREFIX: ${self:custom.table_prefix}
    REDSHIFT_USER: ${self:custom.user}
    REDSHIFT_PASSWORD: ${self:custom.password}
    REDSHIFT_PORT: ${self:custom.port}
    REDSHIFT_ENDPOINT: ${self:custom.endpoint}
    REDSHIFT_ROLE: ${self:custom.role}
  iam:
    role:
      name: s3-to-redshift-load
      statements:
        - Effect: Allow
          Action:
            - s3:GetObject
          Resource: "arn:aws:s3:::${self:custom.bucket}/*"

functions:
  load:
    handler: handler.run
    events:
      - s3: #https://www.serverless.com/framework/docs/providers/aws/events/s3#using-existing-buckets
          bucket: ${self:custom.bucket}
          event: s3:ObjectCreated:*
          rules:
            - prefix: ${self:custom.path_prefix}/
            - suffix: .json
          existing: true

但是当我部署时出现以下错误

Serverless Error ----------------------------------------

  An error occurred: LoadCustomS31 - Received response status [FAILED] from custom resource. Message returned: Configuration is ambiguously defined. Cannot have overlapping suffixes in two rules if the prefixes are overlapping for the same event type. See details in CloudWatch Log: 2021/08/30/[$LATEST]4f4f9ec564544ebb979576ed1b6b2879 (RequestId: 317ecd1c-b699-4799-8060-5168e1947e3c).

知道我在这里做错了什么吗？

Answer 1

在不了解 CloudWatch 日志的详细信息的情况下

2021/08/30/[$LATEST]4f4f9ec564544ebb979576ed1b6b2879 (RequestId: 317ecd1c-b699-4799-8060-5168e1947e3c)

我会说，在您的 AWS 账户中，该存储桶上已经有一个带有前缀

${self:custom.path_prefix}/

和后缀

.json

的 S3 事件。它可能是因为以前或其他无服务器堆栈而存在，或者是有人手动创建它但尚未删除它。

您能否通过 AWS 控制台检查 S3 上是否没有具有相同配置的其他事件？

Answer 2

当我将一个事件函数替换为具有相同前缀的另一个事件函数时，我遇到了这个问题。我通过在没有该事件的任何函数的情况下部署，然后使用该函数重新部署来删除该函数。 我想我可以手动进入控制台并删除该事件......
