Meteor.js错误：从exceptionxGHk6PkFTQ9uv8ncg TypeError：不能调用未定义的方法“查找”

我突然得到以下错误

Exception from sub xGHk6PkFTQ9uv8ncg TypeError: Cannot call method 'find' of undefined at null._handler (app/server/publications.js:6:22) at maybeAuditArgumentChecks (packages/livedata/livedata_server.js:1349) at _.extend._runHandler (packages/livedata/livedata_server.js:796) at _.extend._startSubscription (packages/livedata/livedata_server.js:690) at _.extend.protocol_handlers.sub (packages/livedata/livedata_server.js:508) at packages/livedata/livedata_server.js:472 

publications.js第6行的代码是：

 Meteor.publish('users', function() { return Meteor.users.find( {}, {fields:{'age': 1}} ) }); 

为什么这会导致错误，我们该如何解决？

发现accounts-password突然丢失，导致这个问题。
