Object and array path parameter serialization

[bali182]

Hello again, I come to you with another issue. I'm trying to test an operation with path parameters.

Source of the schema is here: https://github.com/bali182/oats/blob/mocker-example/projects/openapi-e2e-test/kitchenSink.json

When sending primitve type parameters (boolean, string, or number) its working as expected. However when I'm sending array or object parameters I get an error:

[INFO ] < [400] {
    errors: [
      "Invalid path param arrayInPath. Expected value of type array but received 'a,b'",
      "Invalid path param objectInPath. Expected value of type object but received 's,str,b,false,n,1'",
    ],
  }

For this URL: /path-params/foo/1/true/a,b/s,str,b,false,n,1

This is the relevant part of the schema:

{
  "/path-params/{stringInPath}/{numberInPath}/{booleanInPath}/{arrayInPath}/{objectInPath}": {
    "parameters": [
      {
        "name": "stringInPath",
        ...
      },
      {
        "name": "numberInPath",
        ...
      },
      {
        "name": "booleanInPath",
        ...
      },
      {
        "name": "arrayInPath",
        "required": true,
        "in": "path",
        "style": "simple",
        "schema": {
          "type": "array",
          "items": {
            "type": "string"
          }
        }
      },
      {
        "name": "objectInPath",
        "required": true,
        "in": "path",
        "style": "simple",
        "schema": {
          "type": "object",
          "properties": {
            "s": {
              "type": "string"
            },
            "n": {
              "type": "number"
            },
            "b": {
              "type": "boolean"
            }
          }
        }
      }
    ],
    "get": {
      ...
    }
  }
}

Now for serialization, I'm using the simple method in this case described here:
https://swagger.io/docs/specification/serialization/
And I don't have explode on which is the default.

Am I misunderstanding the parameter serialization or is the mocker library expecting path parameters differently?

Thank you,
Balazs

I will have to dig more into this. My guess is that parameters are not being parsed using the style property thus the validation error of string vs object/array
