Error with CLI when generating documentation

[waldo2188]

Swagger2Markup version: 1.3.3

Problem description: I tried to generate an ASCIIDOC with a JSON file made with Swashbuckle for AspNetCore. Swashbuckle provide an API to generate Swagger's json from the code documentation.

The CLI fail with this error

with this content :

{"swagger":"2.0","info":{"version":"v1","title":"My API","description":"My API for yhings","contact":{"name":"plop","email":"[email protected]"}},"paths":{"/email/attachment":{"post":{"tags":["Email"],"summary":"bla","operationId":"EmailAttachmentPost","consumes":[],"produces":[],"parameters":[{"name":"uploads","in":"query","description":"","required":false,"type":"array","items":{},"collectionFormat":"multi"},{"name":"email","in":"query","description":"","required":false,"type":"string"}],"responses":{"200":{"description":"Success"}}}}},"definitions":{"Microsoft.AspNetCore.Http.IFormFile":{"type":"object","properties":{"contentType":{"type":"string","readOnly":true},"contentDisposition":{"type":"string","readOnly":true},"headers":{"type":"object","additionalProperties":{"type":"array","items":{"type":"string"}},"readOnly":true},"length":{"format":"int64","type":"integer","readOnly":true},"name":{"type":"string","readOnly":true},"fileName":{"type":"string","readOnly":true}}}},"securityDefinitions":{"http":{"name":"Authorization","in":"header","type":"apiKey","description":"...."}}}

and this command :

java -jar swagger2markup-cli-1.3.3.jar convert -i swagger_json/emailing-api.json -d out

I have tried with other json made by Swashbuckle and it's work really nice.

I think the problem come from the fact that Microsoft.AspNetCore.Http.IFormFile is an array.

I can confirm this same issue when endpoints take IFormFile Lists/Arrays as parameters.
