OpenApi2 SwaggerUI execute POST sends empty body

[dschulten]

The OpenApi2 SwaggerUI Try Out for POST request appears to be broken, it sends an empty request body. (OpenApi3 works).

This is the resource.json:

{
  "operationId" : "birthCertificate",
  "summary" : null,
  "description" : null,
  "privateResource" : false,
  "deprecated" : false,
  "request" : {
    "path" : "/example",
    "method" : "POST",
    "contentType" : "application/json;charset=UTF-8",
    "schema" : null,
    "headers" : [ ],
    "pathParameters" : [ ],
    "requestParameters" : [ ],
    "requestFields" : [ ],
    "example" : "{\"some\": \"json\"}",
    "securityRequirements" : null
  },
  "response" : {
    "status" : 200,
    "contentType" : "text/xml",
    "schema" : null,
    "headers" : [ ],
    "responseFields" : [ ],
    "example" : "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?>\n<root/>"
  },
  "tags" : [ "sometag" ]
}

Below is the resulting openapi2.yml. It has an empty parameter name for the body, and I suspect that this causes the problem, see https://github.com/swagger-api/swagger-ui/issues/965

Hey @dschulten ,

thanks for reaching out! Would you mind posting the produced OpenAPI3 yml? In your test, are you using a Spring Restdocs field descriptor to document some?

"requestFields" : [ ],

Looks weird to me, rest seems to be fine (example is documented, definition is derived from example, although no real schema since field value/name is not there).
