Bug: sam deploy - AttributeError #7692

Open powlo opened 1 week ago

powlo commented 1 week ago

Description:

A sam template that contains AWS::CloudFormation::Stack instead of AWS::Serverless::Application will report an "Error: 'NoneType' object has no attribute 'startswith'" along with traceback.

Possibly related to https://github.com/aws/aws-sam-cli/issues/6225.

Steps to reproduce:

# template1.yml

AWSTemplateFormatVersion: "2010-09-09"
Transform: AWS::Serverless-2016-10-31

Resources:

  Template2Stack:
    Type: AWS::CloudFormation::Stack
    Properties:
      Location: template2.yml

# template2.yml

AWSTemplateFormatVersion: "2010-09-09"
Transform: AWS::Serverless-2016-10-31

Resources:
  VPC:
    Type: AWS::EC2::VPC
    Properties:
      CidrBlock: 10.192.0.0/16
      EnableDnsSupport: true
      EnableDnsHostnames: true

Observed result:

$ sam validate --template-file template1.yml

template1.yml is a valid SAM Template. This is according to basic SAM Validation, for additional validation, please run with "--lint" option

An unexpected error was encountered while executing "sam deploy". Search for an existing issue: https://github.com/aws/aws-sam-cli/issues?q=is%3Aissue+is%3Aopen+Bug%3A%20sam%20deploy%20-%20AttributeError Or create a bug report: https://github.com/aws/aws-sam-cli/issues/new?template=Bug_report.md&title=Bug%3A%20sam%20deploy%20-%20AttributeError

Expected result:

Expect the template to fail validation, or the output to be more meaningful.
