Research direction

Compare the downloaded vpc_us-west-2 and vpc_us_east_1 YAML templates with the parser location reported at line 208, column 74. Start by validating the selected template using AWS CloudFormation's standard YAML validation and inspect the content shown around that location. Done means the VPC template parses successfully.
