Prism is finding wrong path definition ending on 422 error

I started using prism to mock an ERP OpenAPI, I’m getting 422 errors when trying to get:

http://localhost:4010/companies(f8781b8e-d4cb-3af7-ec00-0d97831c67ed)/salesOrders

I get:

{
    "type": "https://stoplight.io/prism/errors#UNPROCESSABLE_ENTITY",
    "title": "Invalid request body payload",
    "status": 422,
    "detail": "Your request is not valid and no HTTP validation response was found in the spec, so Prism is generating this error for you.",
    "validation": [
        {
            "location": [
                "path"
            ],
            "severity": "Error",
            "code": "required",
            "message": "should have required property 'company_id'"
        },
        {
            "location": [
                "path"
            ],
            "severity": "Error",
            "code": "required",
            "message": "should have required property 'countryregion_id'"
        }
    ]
}

if you see my definition the initial path is requesting this parameters, but prism is the wrong path for some reason,

any ideas why?
