Simple API specs make swagger2markup crash

[gganssauge]

I'm starting with a very simple API to build up my microservice toolchain.

One step of that toolchain is generation of markdown from the swagger spec for my API.

Swagger2Markup seems to be the best option to realize such a step.

Unfortunately Swagger2Markup crashes on my API:

When I omit the SecurityDefinition the generation that crash doesn't happen and an output file is created.

I attached the API spec used to generate the above crash, so it is possible to reproduce the error.

I also have this issue!

It seems that swagger2markup doesn't correctly handle the case where the Oauth2 scopes object is empty. (This was also discussed on another swagger project in swagger-api/swagger-ui#2150)

Hi, sry for the late reply. I'm quite busy atm. Would you like to contribute a fix? Shouldn't be very complex.

Hey I created a pull request for this. Any chance to get a new release including the fix? Thx! https://github.com/Swagger2Markup/swagger2markup/pull/293

[RobWin]

Thx. I have a look at it in Monday.
