Unable to match path params with OpenAPI expectations

[lvijnck]

Describe the issue

I am trying to match path params with the mock library,, but I can't seem to find how to do this.

https://app.swaggerhub.com/apis/jamesdbloom/mock-server-openapi/5.15.x

What you are trying to do

Setup expectations for the OpenAPI generated MockServer

MockServer version
Latest

To Reproduce
Steps to reproduce the issue:

1. How you are running MockServer (i.e maven plugin, docker, etc)

Docker-compose

3. Code you used to create expectations

Schema:

    "/asset-facing/project/{projectId}": {
      "get": {
        "operationId": "ProjectController_getProjectInfo",
        "summary": "Get project information",
        "description": "This endpoint returns the project details along with the users associated with the project and a list of instances.",
        "parameters": [
          {
            "name": "projectId",
            "required": true,
            "in": "path",
            "example": "996e1ac7-8a60-41ec-81a5-36ca72e69f13",
            "schema": {}
          }
        ],
        "responses": {
          "200": {
            ...
         }
    }

 {
    "httpRequest": {
      "specUrlOrPayload": "file:/openapi/core-api.json",
      "operationId": "ProjectController_getProjectInfo",
    },
    "httpResponse": {
      "statusCode": 200,
      "headers": {
        "content-type": [
          "application/json"
        ]
      },
      "body": {
        "nonce": "f1b75ac7689ff88e1ecc40c84b115785"
      }
    }
  }

5. What error you saw

didn't match open api "" operation "ProjectController_getProjectInfo" request matcher:

core_api_1     |  because:
core_api_1     | 
core_api_1     |   method matched
core_api_1     |   path matched
core_api_1     |   body matched
core_api_1     |   headers matched
core_api_1     |   cookies matched
core_api_1     |   pathParameters didn't match
core_api_1     |  

Expected behaviour

Have the ability to specify pathParameters for matching, but that crashes with the following message, e.g.,

"pathParameters" : [
        {
          "name": "projectId",
          "values": [
            "dummy"
          ]
        }
      ]

What version is the OpenAPI spec?
I had the same problem. But while typing some findings here, I tried using OpenAPI spec version 3.0.1 and it worked. Using spec version 3.1.0 doesn't work. Same spec, just changing the version (it is a simple spec).
