aws-cloudformation - CloudFormation - SAM 模板的结构无效。 'Resources' 部分是必需的

Question

我尝试使用代码管道部署 lambda 并使用 sam yml 进行代码部署，但失败并出现以下错误:

FAILED - Transform AWS::Serverless-2016-10-31 failed with: 
Invalid Serverless Application Specification document. 
Number of errors found: 1. Structure of the SAM template is invalid. 
'Resources' section is required

sam.yml 是:

AWSTemplateFormatVersion: '2010-09-09'
Transform: 'AWS::Serverless-2016-10-31'
Description: Lambda1
Resources:
callDetails:
Type: 'AWS::Serverless::Function'
Properties:
  Handler: lambda_function.lambda_handler
  Runtime: python3.6
  CodeUri: .
  Description: 'Lambda Function'
  MemorySize: 128
  Timeout: 30
  Role: 'arn:aws:iam::XXXXXX:role/YYYYYYYYY'
  Environment:
    Variables:
      REGION: ap-southeast-2

buildspec.yml 具有以下命令

aws cloudformation package \
  --template-file samTemplate.yaml \
  --s3-bucket XXXX \
  --output-template-file outputSamTemplate.yaml

输出SamTemplate:

AWSTemplateFormatVersion: '2010-09-09'

Resources:
 callDetails:
  Properties:

就我而言，我有一些 yml 文件，其中的资源 block 为空，删除这些文件解决了问题。
