I copied example 1 from the JsonPartialMatcher wiki into a test.json static mapping file. When I start my wiremock docker container, I get the following error:

habits-mocks | 08/22/2022 01:11:07 [Error] : Static MappingFile : '/app/__admin/mappings/test.json' could not be read. This file will be skipped.

Only thing I've changed is the Guid. For reference, here is the copied file:

{
    "Guid": "3d76d96b-4d95-4a7d-b65d-2b0bbb575329",
    "Request": {
        "Path": {
            "Matchers": [
                {
                    "Name": "JsonPartialMatcher",
                    "Pattern": "/jsonpartialmatcher1"
                }
            ]
        },
        "Methods": [
            "post"
        ],
        "Body": {
            "Matcher": {
                "Name": "JsonMatcher",
                "Pattern": "{ \"test\": \"abc\" }"
            }
        }
    },
    "Response": {
        "StatusCode": 200,
        "Body": "{ \"result\": \"jsonpartialbodytest1\" }",
        "UseTransformer": false
    }
}

And here is a link to the wiki I copied it from: Json mapping option 1

@rosemaryehlers
The example was wrong.
For path, you can only use a string or matcher which implements IStringMatcher (which is fine for e.g. WildcardMatcher)

For the body, you can use a JsonPartialMatcher

"Body": {
            "Matcher": {
                "Name": "JsonPartialMatcher",
                "Pattern": "{ \"test\": \"abc\" }"
            }
        }
