JsonMatcher not working when JSON contains a DateTimeOffset

Hi, I’m trying to match wiremock match on the body of an incoming POST, and am having trouble with DateTimeOffsets.

If we start with the example from the wiki: https://github.com/WireMock-Net/WireMock.Net/wiki/Request-Matching#json-jsonmatcher everything works as expected. A request to /jsonmatcher1 with the body:

{
	x: 42,
	s: "s"
}

works as expected and gives the response.

When I delete that mapping and add a new one with a DateTimeOffset property in the body:

{
    "Guid": "debaf408-3b23-4c04-9d18-ef1c020e79f2",
    "Request": {
        "Path": {
            "Matchers": [
                {
                    "Name": "WildcardMatcher",
                    "Pattern": "/jsonmatcher1"
                }
            ]
        },
        "Methods": [
            "post"
        ],
        "Body": {
            "Matcher": {
                "Name": "JsonMatcher",
                "Pattern": "{ \"x\": 42, \"s\": \"s\", \"preferredAt\": \"2019-11-21T10:32:53.2210009+00:00\" }"
            }
        }
    },
    "Response": {
        "StatusCode": 200,
        "Body": "{ \"result\": \"jsonbodytest\" }",
        "UseTransformer": false
    }
}

and send the same request as before, but now with body:

{
	x: 42,
	s: "s",
	preferredAt: "2019-11-21T10:32:53.2210009+00:00"
}

it doesn’t work (returns {"Status": "No matching mapping found"}).

I assume wiremock.net is doing some special processing on these DateTimeOffset values and it isn’t working in this case, or am I doing something wrong? Also: Is there any way of making wiremock.net treat these as strings and just compare them as strings? For my current use-case that would suffice. Cheers, Josh

“Build StandAlone.NETCoreApp” is probably there to quickly check if the code can build.

Cool that it works, I will close this issue and a new official NuGet + docker will be released in few days. Just keep watching this project or dockerhub.

This looks a lot like https://github.com/WireMock-Net/WireMock.Net/issues/347

I’ll investigate the JsonMatcher code…
