Taskcat upload fails without proper error log

[swagatbora90]

Hi team,

I am running taskcat upload to package and upload my project to an S3 bucket. However, when I have add multiple regions in my .taskcat.yml file, then the upload fails without any debug logs on the region that caused the failure.

Here is my current .taskcat.yml file:

project:
  name: cfn-ecr-aws-soci-index-builder
  owner: [email protected]
  s3_regional_buckets: true
  lambda_source_path: functions/source
  lambda_zip_path: functions/packages
  parameters:
    QSS3BucketName: $[taskcat_autobucket]
    QSS3KeyPrefix: "cfn-ecr-aws-soci-index-builder/"
    SociRepositoryImageTagFilters: "*:*"
tests:
  can-deploy:
    regions:
      - us-east-1
      - eu-west-1
      - us-west-1
      - ap-southeast-1
      - ap-northeast-1
      - us-west-2
      - sa-east-1
      - ap-southeast-2
      - eu-central-1
      - ap-northeast-2
      - ap-south-1
      - us-east-2
      - ca-central-1
      - eu-west-2
      - eu-west-3
      - ap-northeast-3
      - eu-north-1
      - me-south-1
      - eu-south-1
      - af-south-1
    template: templates/SociIndexBuilder.yml

Here is the error log:

Expectation

Region name should be displayed in the error log to help debug the issue
