Apimocker crashes when mockFile is missing

[platan]

Apimocker (v.0.4.0) crashes when required element mockFile is missing for webservice:

{
    "mockDirectory": "/home/me/apimocker",
    "quiet": false,
    "port": "8300",
    "webServices": {
        "items/1": {
            "verbs": ["get"]
        }
    }
}

$ apimocker -c config.json

Maybe it should return 5xx server error HTTP status code insted?

Good suggestion - it should probably return a 500 error. This seems like a fix that would be pretty simple. I'm pretty busy right now, but I'll try to get it in soon. Also, pull requests are welcome!

Fixed in apimocker v0.4.1.
