Can't import Postman Collections

[allreddv]

I am trying to import Postman collections but can't get it to work. I have exported a collection from Postman confirming using v2.1,

I run the command
─ atac -d api-collections import postman filename.postman_collection.json

and i get an error of
Could not parse JSON collection "api-collections/lds_website.postman_collection.json"
missing field name at line 36 column 1

    which is strange as line 36 is just the final closing bracket.  I have confirmed there isn't any extra blank lines.  Ran the json in JSONLint just to confirm it is a valid json.  

Any ideas?
