node.js + express error：無法讀取undefined的屬性'url'

我對Node.js相當陌生，安裝它來試用DrupalChat（v7dev）模塊。我相信這個問題與node.js或express相關，因爲我超出了聊天模塊設置加載的階段。我試圖啓動聊天服務器node.js + express error：無法讀取undefined的屬性'url'

Extension loaded: drupalchat_nodejs.server.extension.js 
Started http server. 
    info - socket.io started 

node.js:201 
     throw e; // process.nextTick error, or 'error' event on first tick 
      ^
TypeError: Cannot read property 'url' of undefined 
    at Function.handle (/usr/local/lib/node_modules/npm/node_modules/express/node_modules/connect/lib/proto.js:105:18) 
    at Server.app (/usr/local/lib/node_modules/npm/node_modules/express/node_modules/connect/lib/connect.js:60:31) 
    at Server.serverListening (/usr/local/lib/node_modules/npm/node_modules/socket.io/node_modules/policyfile/lib/server.js:136:16) 
    at Server.g (events.js:154:14) 
    at Server.emit (events.js:64:17) 
    at Array.1 (net.js:710:10) 
    at EventEmitter._tickCallback (node.js:192:40)

我記得快遞安裝的時候，它給了像」警告....錯誤[‘網絡’]也許應該是bug ['URL時面臨以下輸出']「（我不記得前綴）

因此，服務器試圖讀取（API？）變量'url'，但它目前'web'？

我有所有的模塊是最新的，是我應該降級？或者有什麼方法來解決這個使用另一個模塊？

編輯：線201是最後很行（刪除authenticatedClients [authData.authToken];）...我只是加全功能適當的上下文

var authenticateClientCallback = function (error, response, body) { 
    if (error) { 
    console.log("Error with authenticate client request:", error); 
    return; 
    } 
    if (response.statusCode == 404) { 
    if (settings.debug) { 
     console.log('Backend authentication url not found, full response info:', response); 
    } 
    else { 
     console.log('Backend authentication url not found.'); 
    } 
    return; 
    } 

    var authData = false; 
    try { 
    authData = JSON.parse(body); 
    } 
    catch (exception) { 
    console.log('Failed to parse authentication message:', exception); 
    if (settings.debug) { 
     console.log('Failed message string: ' + body); 
    } 
    return; 
    } 
    if (!checkServiceKey(authData.serviceKey)) { 
    console.log('Invalid service key "', authData.serviceKey, '"'); 
    return; 
    } 
    if (authData.nodejsValidAuthToken) { 
    if (settings.debug) { 
     console.log('Valid login for uid "', authData.uid, '"'); 
    } 
    setupClientConnection(authData.clientId, authData, authData.contentTokens); 
    authenticatedClients[authData.authToken] = authData; 
    } 
    else { 
    console.log('Invalid login for uid "', authData.uid, '"'); 
    delete authenticatedClients[authData.authToken]; 
    } 
}

，你能否告訴Node.js的：201或者更多一點。 – malletjo 2012-04-16 15:12:21

我添加了它，現在我想知道它是否在開發人員可能要求的DrupalChat配置中的非必需設置（serviceKey），但沒有反映在他的代碼/註釋 – 2012-04-16 15:38:32

v7中並不穩定，您可能會發現這裏的東西：http://drupal.org/project/issues/drupalchat?status=All&categories=全部 – malletjo 2012-04-16 15:46:02
