Ungit stopped working on Chrome 57

The recent version of Chrome gives me the “Whooops - Something went wrong, reload the page to start over.” message. The same server & directory works in Firefox. Chrome private mode does not fix it either. Accessing both via localhost or 127.0.0.1 do not work in chrome, both work in Firefox.

Versions:

• OS: Arch Linux
• chrome: 57.0.2987.110 (64-bit)
• firefox: 52.0 (64-bit)
• node: 6.10.1
• npm: 4.4.1
• ungit: 1.1.11

My server.log (via ungit --logRESTRequests --logGitCommands --logGitOutput) Chrome’s browser console output. Any other Information I can provide?

by the way: very nice work on ungit!

I had the same issue. One of my ad blockers was breaking ungit: uBlock Origin. After disabling it on localhost everything went back to normal.

The error thrown seems to be caused by an XHR returning status 0 for GET /api/log in server.js:

Server.prototype._httpJsonRequest = function(request, callback) {
  var httpRequest = new XMLHttpRequest();
  httpRequest.onreadystatechange = function() {
    // It seems like you can get both readyState == 0, and readyState == 4 && status == 0 when you lose connection to the server
    if (httpRequest.readyState === 0) {
      callback({ error: 'connection-lost' });
    } else if (httpRequest.readyState === 4) {
      var body;
      try {
        body = JSON.parse(httpRequest.responseText);
      } catch(ex) { body = null; }
      if (httpRequest.status == 0) {
      	callback({ error: 'connection-lost' });  // <--- error is thrown here
      }
      else if (httpRequest.status != 200) callback({ status: httpRequest.status, body: body, httpRequest: httpRequest });
      else callback(null, body);
    }
  }
  var url = request.url;
  if (request.query) {
    url += '?' + this._queryToString(request.query);
  }
  httpRequest.open(request.method, url, true);
  httpRequest.setRequestHeader('Accept', 'application/json');
  if (request.body) {
    httpRequest.setRequestHeader('Content-Type', 'application/json');
    httpRequest.send(JSON.stringify(request.body));
  } else {
    httpRequest.send(null);
  }
}

Properties of request:

{
    "method": "GET",
    "url": "/api/log",
    "query": {
        "path": "/home/leon/Development/immutablets",
        "limit": 25,
        "skip": 0,
        "socketId": 0
    }
}

Opening the endpoint directly in a new tab returns HTTP 200 and a proper JSON body.

I can reproduce it on every run, if I can provide any more information to narrow it down, let me know.
