Angular-Meteor 1 helper: Error: Item xxxxxx already present in OrderedDict

Hey guys,

I have this issue on my app but I’ve been able to reproduce it on the completed angularjs meteor tutorial found here https://www.meteor.com/tutorials/angular/creating-an-app

Exception in queued task: Error: Item 5a395ec67e5d23beb3ce21c7 already present in OrderedDict

All I’ve done is added an input field in the template and take it as a regex in the helpers, as below:

    this.helpers({
      tasks() {
        const selector = {};

        if (this.getReactively('text')) {
          selector.text = {
            $regex: '.*'+this.text+'.*',
            $options: 'i'
          };
        }

        return Tasks.find(selector, {
          sort: {
            createdAt: -1
          }
        });
      },
...

So as you fill the text field the correct results are returned. The error occurs when you empty the text field. I could stick it into a method but that would lose the reactivity aspect.

If you could help it’d be greatly appreciated!
