any idea how to solve that ? is there an easier way to prettify the swagger file? because i get many parsing erros. also does any one have a good example of using swagger with express and mongodb ? many thanks.

Answer 1

One of the references is missing a / after #:

$ref: "#definitions/Employee"

Change it to:

$ref: "#/definitions/Employee"
#       ^

If you paste your definition into http://editor.swagger.io, it shows where exactly the error is.
