Help please,

I’m receiving an error after saving the playlist on Spotify:

Here is my App.js:

import React from "react";
import "./App.css";

import SearchBar from "../SearchBar/SearchBar";
import SearchResults from "../SearchResults/SearchResults";
import Playlist from "../Playlist/Playlist";

import Spotify from "../../util/Spotify";

class App extends React.Component {
  constructor(props) {
    super(props);

    this.state = {
      searchResults: [],
      playlistName: "My Playlist",
      playlistTracks: []
    };
    this.addTrack = this.addTrack.bind(this);
    this.removeTrack = this.removeTrack.bind(this);
    this.updatePlaylistName = this.updatePlaylistName.bind(this);
    this.savePlaylist = this.savePlaylist.bind(this);
    this.search = this.search.bind(this);
  }

  addTrack(track) {
    let tracks = this.state.playlistTracks;
    if (tracks.find(savedTrack => savedTrack.id === track.id)) {
      return;
    }

    tracks.push(track);
    this.setState({ playlistTracks: tracks });
  }

  removeTrack(track) {
    let tracks = this.state.playlistTracks;
    tracks = tracks.filter(currentTrack => currentTrack.id !== track.id);

    this.setState({ playlistTracks: tracks });
  }

  updatePlaylistName(name) {
    this.setState({ playlistName: name });
  }

  savePlaylist() {
    const trackUris = this.state.playlistTracks.map(track => track.uri);
    Spotify.savePlaylist(this.state.playlistName, trackUris).then(() => {
      this.setState({
        playlistName: "New Playlist",
        playlistTracks: []
      });
    });
  }

  search(term) {
    Spotify.search(term).then(searchResults => {
      this.setState({ searchResults: searchResults });
    });
  }

  render() {
    return (
      <div>

Thank you

Hi Emmanuel,

there is a typo in Spotify.js:

savePlalist(name, …) instead of Playlist(name, …).

Thank you very much for catching it. I appreciate it
