The add lyrics query returns an error but saves in the database

[Jay-Topher]

I believe there's an issue either with the db model or the addLyrics mutation

[vishalisakar]

yes. I'm also having the same issue.

Anyone with answers should please notify us here, so we can move forward with the course, this is a huge blocker

How far along are you in the video?

[Jay-Topher]

I'm currently in Client side graphql >> working through the schema

[Jay-Topher]

That should be the fourth video of the 6th section

So you cloned the repo, are you using monogodb atlas? https://www.mongodb.com/cloud/atlas

Finally, I got the solution.
Thank you @PostIt59, by your solution only I could solve it.

I hope u can try this or you can check his solution in issue page at #17

In server/models/song.js just add:

usePushEach : true

onst SongSchema = new Schema({
  title: { type: String },
  user: {
    type: Schema.Types.ObjectId,
    ref: 'user'
  },
  lyrics: [{
    type: Schema.Types.ObjectId,
    ref: 'lyric'
  }]
}, {
  usePushEach : true
});

then change the addLyric as follows

song.lyrics.push(lyric) to song.lyrics.push(lyric.id)

SongSchema.statics.addLyric = function(id, content) {
  const Lyric = mongoose.model('lyric');

  return this.findById(id)
    .then(song => {
      const lyric = new Lyric({ content, song })
      song.lyrics.push(lyric.id)
      return Promise.all([lyric.save(), song.save()])
        .then(([lyric, song]) => song);
    });
}
