Spotify API OAUTH2 Server Error Response when requesting token

Question

Spotify Oauth2 Docs - Client Credential Flow

I asked a similar question, and I was able to get the code running in google apps script (javascript). I am using Client Credential Flow. However, I tried to recreate this code in Nodejs. When running this code, I receive a server error.

 error: "server_error"

This is the problem code in Nodejs

 const defaultConfig = { method: 'POST', headers: { 'Content-Type': 'application/json', 'Accept': 'application/json', // this encodes the app_id and api_key into a base64 string like the documentation states 'Authorization': `Basic ${btoa(spotify.API_ID + ':' + spotify.API_KEY)}` }, body: JSON.stringify({ 'grant_type': 'client_credentials', }) }; // this function is wrapped in a list titled, "apiSettings" with other functions. I just included the authorization function here: const apiSettings = { getSpotifyAuthorizeToken: async () => { const endpoint = "https://accounts.spotify.com/api/token"; return await (await fetch(endpoint, defaultConfig)).json(); }, };

I got this similar code to work in google apps script with no problems.

Could the server error be a result of me running Nodejs on a "localhost:xxxx"? The documentation states that, "The Client Credentials flow is used in server-to-server authentication."

if this is not the case, could you provide a working

Spotify API OAUTH2 Server Error Response when requesting token

From your previous question , I would like to propose the following sample scripts.

Sample script 1:

If you want to convert the script of this answer to Node.js and node-fetch, how about the following script?

const spotify = { API_ID: "API_ID", API_KEY: "API_KEY" }; // Please set your client ID and client secret.

const buf = Buffer.from(spotify.API_ID + ":" + spotify.API_KEY);
const para = new URLSearchParams();
para.append("grant_type", "client_credentials");
const defaultConfig = {
  method: "POST",
  headers: { Authorization: `Basic ${buf.toString("base64")}` },
  body: para,
};
const apiSettings = {
  getSpotifyAuthorizeToken: async () => {
    const endpoint = "https://accounts.spotify.com/api/token";
    return await (await fetch(endpoint, defaultConfig)).json();
  },
};

Sample script 2:

const spotify = { API_ID: "API_ID", API_KEY: "API_KEY" }; // Please set your client ID and client secret.

para.append("grant_type", "client_credentials");
para.append("client_id", spotify.API_ID);
para.append("client_secret", spotify.API_KEY);
const defaultConfig = {

const apiSettings = {
  getSpotifyAuthorizeToken: async () => {
    const endpoint = "https://accounts.spotify.com/api/token";
    return await (await fetch(endpoint, defaultConfig)).json();
  },
};
