Ran just retirejs scan on a project. The screen showed retire.js finding some issues but then hitting an error. unfortunately the glue output json was just [] So if you were just processing the output it would probably not indicate there were any errors.
Log shows
RetireJS scanning: /mnt/project
Missing version for popper.js. Need to run npm install ?
Retire JSON Raw Results: [{ A BUNCH OF RESULTS HERE }]
Problem running RetireJS
#<NoMethodError: undefined method `each_with_object' for nil:NilClass>
And like I mentioned earlier the output .json file contains just []
