Unhandled exception in swagger_params_parser.js

[szilveszterb]

I'm using swagger-express-mw v0.7.0 with swagger.
I have an endpoint consuming content type multipart/form-data and it has a parameter with type file.

If I do a POST to that endpoint with content type multipart/form-data and I deliberately omit the file as a test, then an Exception is thrown from the getValue function in swagger_params_parser.js, line 40:

params[parameter.name] = parameter.getValue(req); // note: we do not check for errors here

In that case next() is never called.

A try - catch around that code would solve the issue.
Let me know if this was an acceptable solution.

The error log:

Error: req.files must be provided for 'formData' parameters of type 'file'
