Angular Tutorial Step 9 Runtime Error

[jannon]

I'm just going through the Angular tutorial and encountered an error after completing step 9, switching to methods for security. The error is as follows:

Exception while invoking method 'tasks.setChecked' Error: Match error: Expected string, got object

The following code was added in step 9:

'tasks.setChecked' (taskId, setChecked) {
    check(taskId, String);
    check(setChecked, Boolean);

    Tasks.update(taskId, {
      $set: {
        checked: setChecked
      }
    });

Basically, it considers taskId (passed in as task._id) to be an object instead of a String so the check fails. Commenting out the check eliminates the error.

So (1) something might need to be changed in the tutorial and (2) why does it fail on the setChecked method, but not on the remove method?

I also have this problem, doing tutorial step-by-step... (Angularjs todos)

I have the same issue - Meteor todos Tutorial

I guess the reason is that you'r created that task from meteor-mongo console. For some reason it creating object instead of string. I have same issue

I'm having the same issue. I can confirm @massanchik guess. I'm doing the blaze tutorial, but that is irrelevant since the issue is with the MongoDB not the templating engine.

Below is a view from Robomongo 0.8.4 of the tasks collection, notice how documents 1-3 show ObjectId("[id]") as the Key field.

I had a similar issue, afterwards I discovered it related to items created before that change. To solve, delete all existing records.

'meteor mongo' 'db.tasks.remove( { } )'

Resolution

Ok, this seems to be MongoDB's standard behaviour if the _id field is not specified whe inserting the document (record).

Work Around

Delete all records before starting this step.

meteor mongo
db.tasks.remove( { } )

Next Steps

• Update documentation on previous steps to specify the _id when inserting records,

or

• Add a step to delete all records before starting Step 9
