Expected Behavior

I expect my request body value, shown below, to be serialized correctly.

{
  "id": "string",
  "address": {}
}

Current Behavior

The address object is not properly serialized before the request is sent:

Possible Solution

Non-primitive values should be serialized correctly, here: https://github.com/swagger-api/swagger-js/blob/2a3f113c1c219ec3756a73ffc35e366987ff6f5c/src/execute/oas3/build-request.js#L47

I am also having a problem with form data in Try It Out.

Using swagger-ui 3.4.2
OAS3 spec: https://raw.githubusercontent.com/banders/api-specs/upgrade-to-openapi3/jobposting/jobposting.json
(See the POST /jobs operation)

Clicking the execute button using the default request body results in a Javascript error on the page.

@banders this seems closely related, so I'll look into that as well. Sorry for the inconvenience!

[banders]

@shockey I'm still seeing the same problem I reported in the Nov 3 post.

Using swagger-ui 3.6.0
OAS3 spec: https://raw.githubusercontent.com/banders/api-specs/upgrade-to-openapi3/jobposting/jobposting.json
(See the POST /jobs operation)

"Try it Out" then "execute" results in a jvascript error.

If you think this is unrelated to the original issue, I can write it up as new issue.
