Error caught on publication: notes : Can't publish a cursor from a collection without a name

1

Hi, I’m getting an error when trying to subscribe to my publication.

I’m not quite sure where it’d be coming from, and googling didn’t give much relevant results.

So I have

this collection

export const Notes = new Mongo.Collection('notes');

publication

Meteor.publish('notes', function allNotesPublication () {
  check();
  return Notes.find({}, {fields: {text: 1, _id: 1}});
});

Then I’m subscribing with vue-meteor-tracker

export default {
  data () {
    return {
      newNote: '',
      notes: [],
    }
  },

  meteor: {
    $subscribe: {
      'notes': [],
    },
    notes () {
      return Notes.find({}, {
        sort: { created: -1 },
      })
    },
  },

  methods: {
    async addNote () {
      if (this.newNote) {
        try {
          await Meteor.callPromise('notes.add', {
            text: this.newNote,
          })
          this.newNote = ''
        } catch (e) {
          console.error(e)
        }
      }
    },

    async removeNote (note) {
      try {
        await Meteor.callPromise('notes.remove', {
          _id: note._id,
        })
      } catch (e) {
        console.error(e)
      }
    },
  },
}

When it hits the publication it fails with server error “W20190907-23:34:08.437(2)? (STDERR) error caught on publication: notes : Can’t publish a cursor from a collection without a name.”

hope somebody could give a hint…

Looks like your Notes collection has no name. Can you post the code where you declare the collections please.

4

Sure, please see updated post.

5

Very weird. Are you getting the error on the server or client?

6

Yes, that’s on server. I’m trying to find out which package would that be coming from… No clue so far. On the good side publication still seems to work.

I am having the same issue with akryum:vue-ssr. When the server provides the the SSR page I am seeing this error message in the console

The error is actually generated in the meteor/minimongo package _publishCursor(subscription) function.

My hunch is that when using vue-ssr, the server calls this publish function with a LocalCollection instead of the real one, and a local collection does not have a name.

Everything still works, the message is annoying though.

Was actually troubleshooting a different issue and am facing the same problem. @jamgold your hunch is correct I think:

This is from vue-ssr/server/context.js

  getCollection (collName) {
    let collection = this._collections[collName]
    if (!collection) {
      const minimongo = Package.minimongo
      collection = this._collections[collName] = new minimongo.LocalCollection()
    }

    return collection
  }

I will check on how to fix this

Edit
Looking at it, but it seems that FlowRouter has similar code, since its based on that:
