sam deploy Issue - S3 TemplateURLs transformed to local file path #2779
Description
This issue occurs when running sam deploy.
There is a very similar issue that was fixed approx a year ago when running sam build:
#1839
I did place a comment on that closed issue
Description:
sam deploy transforms TemplateURL from S3 https link to local file path. It prepends the path from which the sam deploy command is run to the https link. Then, of course, it says the resulting TemplateURL is invalid.
The example provided is a basic CFN template to show the output but have seen this on full SAM templates with SAM resources as well.
Steps to reproduce:
AWSTemplateFormatVersion: '2010-09-09'
Transform: myTransform
Description: A test CFN template
Resources:
ExampleNestedStack:
Type: AWS::CloudFormation::Stack
Properties:
TemplateURL: https://mybucket.s3.amazonaws.com/20210326_222039_m2/templates/Template/exampletemplate.y\
aml
- note that mybucket is not actual name of the bucket
sam deploy --role-arn my-admin-role --capabilities CAPABILITY_IAM --template-file Template/sample-template.yaml --stack-name my-sample-stack
Observed result:
Error: Unable to upload artifact https://mybucket.s3.amazonaws.com/20210326_222039_m2/templates/Template/exampletemplate.yaml referenced by TemplateURL parameter of ExampleNestedStack resource.
TemplateURL parameter of ExampleNestedStack resource is invalid. It must be a S3 URL or path to CloudFormation template file.
Actual: /home/ec2-user/project/myproj/Template/https:/mybucket.s3.amazonaws.com/20210326_222039_m2/templates/Template/exampletemplate.yaml
Expected result:
successful interpretation and deploy processing of TemplateURL as the provided https path, with no prepending:
https:/mybucket.s3.amazonaws.com/20210326_222039_m2/templates/Template/exampletemplate.yaml
