I’m having a similar problem using a SAM template that I’ve been using for months. Based on the error message its difficult to know where to start looking for the problem. I’d also suggest that if a template is readily accepted by ‘aws cloudformation package’, it should probably be accepted by SAM local:

sam validate --template sam-airmile-with-stack-dependency.yml 2017/08/15 10:05:47 0.1.0 ERROR: Failed to read the resources line numbers. This usually means that the template contains invalid indentation. Please check it and try again

btw, if I pass the yaml file through http://www.yamllint.com/, it tells me the yaml is valid and reformats it; SAM local is happy with the reformatted output.
