"Meteor code must always run within a Fiber" when calling Collection.insert on server

Question

I have the following code in server/statusboard.js; ``` var require = __meteor_bootstrap__.require, request = require("request") function getServices(services) { services = []; request('http://some-server/vshell/index.php?type=services&mode=json', function (error, response, body) { var resJSON = JSON.parse(body); _.each(resJSON, function(data) { var host = data["host_name"]; var service = data["service_description"]; var hardState = data["last_hard_state"]; var currState = data["current_state"]; services+={host: host, service: service, hardState: hardState, currState: currState}; Services.insert({host: host, service: service, hardState: hardState, currState: currState}); }); }); } Meteor.startup(function () { var services = []; getServices(services); console.log(services); }); ``` Basically, it's pulling some data from a JSON feed and trying to push it into a collection. When I start up Meteor I get the following exception; ``` app/packages/livedata/livedata_server.js:781 throw except…

Accepted Answer

As mentioned above it is because your executing code within a callback.

Any code you're running on the server-side needs to be contained within a Fiber.

Try changing your getServices function to look like this:

```
function getServices(services) {
  Fiber(function() { 
    services = [];
    request('http://some-server/vshell/index.php?type=services&mode=json', function (error, response, body) {
      var resJSON = JSON.parse(body);
       _.each(resJSON, function(data) {
         var host = data["host_name"];
         var service = data["service_description"];
         var hardState = data["last_hard_state"];
         var currState = data["current_state"];
         services+={host: host, service: service, hardState: hardState, currState: currState};
         Services.insert({host: host, service: service, hardState: hardState, currState: currState});
      });
    });
  }).run();  
}
```

I just ran into a similar problem and this worked for me. What I have to say though is that I am very new to this and I do not know if this is how this should be done.

You probably could get away with only wrapping your insert statement in the Fiber, but I am not positive.
