无服务器框架-无法为任务状态生成IAM策略语句

Question

我正在尝试使用无服务器框架来部署一个调用几个lambda的step函数。这是我的无服务器。yml:

org: bizrob
app: flexipod-2-queue
service: flexipod-2-queue

frameworkVersion: "2 || 3"

custom:
region: eu-west-1

provider:
name: aws
runtime: nodejs14.x

plugins:
- serverless-step-functions

functions:
pullSqlSvr:
handler: flexipod-2-queue/pullSqlSvrData.pullSqlSvr
environment:
REGION: ${self:custom.region}
API_VERSION_S3: "2006-03-01"
API_VERSION_SQS: "2012-11-05"
SQS_QUEUE_URL: !Ref "MyQueue"
sendToDataLake:
handler: queue-2-datalake/sendToDataLake.sendBatchToQueue
environment:
REGION: ${self:custom.region}
API_VERSION_S3: "2006-03-01"
API_VERSION_SQS: "2012-11-05"

stepFunctions:
stateMachines:
flexipodFlow:
name: flexipodFlow
definition:
StartAt: pullSqlSvr
States:
pullSqlSvr:
Type: Task
Resource:
Fn::GetAtt:[pullSqlSvr, Arn]
Next: sendToDataLake
sendToDataLake:
Type: Task
Resource:
Fn::GetAtt:[sendToDataLake, Arn]
End: true

resources:
Resources:
MyQueue:
Type: "AWS::SQS::Queue"
Properties:
QueueName: "flexipod"

当我运行无服务器部署时，我看到以下错误：

将flexipod-2队列部署到stage dev(us-east-1，"无服务器管理-2"；provider(无法生成IAM策略声明对于任务状态｛Type:"Task"，资源："Fn:：GetAtt:[pullSqlSvr，Arn]'，Next:"sendToDataLake"｝无法生成IAM策略声明对于任务状态｛Type:"Task"，资源："Fn:：GetAtt:[sendToDataLake，Arn]'，结束：true｝

有关于如何解决的建议吗？

Answer 1

这是一个YAML语法问题。Fn::GetAtt:[pullSqlSvr, Arn]被解析为字符串，而不是键值对。在最后一个冒号后添加空格，或使用!GetAtt快捷方式。

Resource:
Fn::GetAtt:[pullSqlSvr, Arn] # string :(
Fn::GetAtt: [pullSqlSvr, Arn] # key-value :)
!GetAtt pullSqlSvr.Arn # alternative shorthand intrinsic function :)

Answer 2

根据我的经验，如果Steps块中的任何键以小写字母开头，serverless-step-functions将无法正确部署。将其更改为看似区分大小写的等价物，如以下内容，并重新部署可能会奏效：

States:
PullSqlSvr:
Type: Task
Resource:
Fn::GetAtt:[pullSqlSvr, Arn]
Next: sendToDataLake
SendToDataLake:
Type: Task
Resource:
Fn::GetAtt:[sendToDataLake, Arn]
End: true

(我刚刚将pullSqlSvr和sendToDataLake转换为它们的PascalCase等价物PullSqlSvr和SendToDataLake。(
