Bad respond when trying to get authentication token for Reddit api 'Application Only OAuth'

So i been trying to get access to the reddit api.
I registered to reddit. verified my mail. opened an app and got my credentials.
Followed this official documentation and also came across to this tutorial
All my efforts have failed and don't get any respond.
I am using nodejs. but also tried in postman and failed.
Tried 2 options using fetch and using axios:
const axios = require('axios');
const fetch = require('node-fetch')
const { URLSearchParams } = require('url')
class RedditApi {
clientId2 = "get ur own credentials by opening an app here https://www.reddit.com/prefs/apps";
clientSecret2 = "get ur own credentials by opening an app here https://www.reddit.com/prefs/apps";
authenticationUrl = `https://www.reddit.com/api/v1/access_token`;
BASE_URL = 'https://www.reddit.com/';
tokenAuth = null;
tokenExpirationTime = null;
currencyObj = null;
constructor(currencyObj) {
this.currencyObj = currencyObj;
console.log("constructor service")
}
async getAuthToken() {
const bodyParams = new URLSearchParams({
grant_type: "https://oauth.reddit.com/grants/installed_client",
device_id: "DO_NOT_TRACK_THIS_DEVICE"
});
console.log(this.clientId2, 'this.clientId');
debugger;
const headersObj = {
'Authorization': `Basic ${Buffer.from(`${this.clientId2}:`).toString('base64')}`,
'Content-Type': 'application/x-www-form-urlencoded',
};
let response = null;
try {
response = await axios.post(this.authenticationUrl,
bodyParams,
{
headers: headersObj
});
debugger;
} catch (error) {
debugger;
console.error(error);
console.log(error.stack);
return null;
}
}
async getAuthToken2() {
try {
// Creating Body for the POST request which are URL encoded
const params = new URLSearchParams()
params.append('grant_type', 'https://www.reddit.com/api/v1/access_token')
params.append('device_id', 'DO_NOT_TRACK_THIS_DEVICE')
// Trigger POST to get the access token
const tokenData = await fetch('https://oauth.reddit.com/grants/installed_client', {
method: 'POST',
body: params,
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'Authorization': `Basic ${Buffer.from(`${this.clientId2}:`).toString('base64')}` // Put password as empty
}
}).then(res => {
debugger;
return res.text()
})
debugger;
if (!tokenData.error) {
debugger;
res.send(trendingResult)
}
res.status(tokenData.error).send(tokenData.message)
} catch (error) {
debugger;
console.log(error)
}
}
}
module.exports = RedditApi;
when using axios i get this respond: "Request failed with status code 401"
When using fetch i get this respond: "'403 Forbidden\nRequest forbidden by administrative rules.\n\n'"
Anybody knows what is the problem and how can i fix it?
Many thanks!

how to fix uri undefined error when trying to send request

when I'm trying to call the request in front node, I'm getting error in my backend node " RequestError: Error: Invalid URI "undefined"" , it seems like backend node request is not getting the data form my frontend node request.
knowing that uploadLink already have a value and in my browser console the frontend request looks ok
my backend request code
const ThumbnailUpload = async (req, res) => {
const { Uploadlink } = req.body;
const { selectedFile } = req.body;
const clientServerOptions = {
uri: `${Uploadlink}`,
body: JSON.stringify({
name: selectedFile,
}),
method: 'PUT',
headers: {
'Content-Type': ' application/json',
Accept: 'application/vnd.vimeo.*+json;version=3.4',
Authorization: getVimeoAuthorization(),
},
};
request(clientServerOptions, function (error, response) {
if (error) {
res.send(error);
} else {
const body = JSON.parse(response.body);
res.send(body);
}
console.log(Uploadlink);
});
};
and my frontend code is
const handleSubmit = (event) => {
event.preventDefault();
const formData = new FormData();
formData.append(
'selectedFile',
new Blob([selectedFile], { type: 'image/jpg, image/png, or image/gif' }),
);
formData.append('uploadLink', uploadLink);
const headers = {
'Content-Type': 'image/jpg, image/png, or image/gif',
Accept: 'application/vnd.vimeo.*+json;version=3.4',
};
try {
axios
.post(`${backendPostPath}/thumbnail-upload`, formData, {
headers,
})
.then((response) => {
applyThumbnial();
console.log(response);
});
} catch (error) {
console.log(error);
}
};
any advise ?

change:
const { Uploadlink } = req.body;
to:
const { uploadlink } = req.body;
make variable consistent throughout the code
EDIT
also, since you're uploading a file, you need to use upload middleware before request handler, and file will be within req.file:
route.post('/thumbnail-upload', upload.single('selectedFile'), ThumbnailUpload);
//... handler..
const selectedFile = req.file;

How to resolve Empty error with status code 500 axios?

this is my code :
Express Routes:
router.route('/block')
.post(controller.ticketBlocking);
Express Controller:
const axios = require('axios');
const OAuth = require('oauth-1.0a');
const crypto = require('crypto');
const ticketBlocking = (req, res) => {
const data = JSON.stringify({
source = req.body.source
});
const oauth = OAuth({
consumer: {
key: '....', //Hided the key
secret: '....', //Hided the secret
},
signature_method: 'HMAC-SHA1',
hash_function(base_string, key) {
return crypto.createHmac('sha1', key).update(base_string).digest('base64');
}
});
const request_data = {
url: 'http://link.vvv/blockTicket',
method: 'post',
};
axios({
method: request_data.method,
url: request_data.url,
headers: {
'Content-Type': 'application/json',
Accept: 'application/json',
...oauth.oauth.toHeader(oauth.oauth.authorize(request_data)),
},
data : data
})
.then((response) => {
console.log(JSON.stringify(response.data));
})
.catch(function (error) {
if (error.response) {
console.log(error.response.data);
console.log(error.response.status);
} else if (error.request) {
console.log(error.request);
} else {
console.log('Error', error.message);
}
console.log(error.config);
});
};
the npm package which am using is - "oauth-1.0a"
The problem am facing is, when i use GET method with different end point, i get an output but when ever i use POST method am getting an empty error with status code 500
I dont know where is the mistake, am using oauth1.0a for authorization, please help !

2 API Calls in One JavaScript

presently I am attempting to make 2 different api calls one after the other within 1 java/nodejs script. It seems after my first function runs successfully, the second one errors with the following:
FetchError: request to failed, reason: socket hang up;
type: 'system',
errno: 'ECONNRESET',
code: 'ECONNRESET'
Below is a code snippet of what I have tried thus far:
const fetch = require("node-fetch");
const formData = require("form-data");
const fs = require("fs");
//const express = require("express");
var apiName = "<LOCAL SYSTEM FILE TO UPLOAD>";
var lookupName = "<LOCAL SYSTEM FILE TO UPLOAD>";
var accessToken = "Bearer <ACCESS TOKEN>";
var url = '<URL API #1>';
var url2 = '<URL API #2>;
var headers = {
'Accept': 'application/json',
'Authorization': accessToken,
};
const form = new formData();
const buffer2 = fs.readFileSync(lookupName);
const buffer = fs.readFileSync(apiName);
const uploadAPI = function uploadAPI() {
form.append("Content-Type", "application/octect-stream");
form.append('file', buffer);
fetch(url, {method: 'POST', headers: headers, body: form})
.then(data => {
console.log(data)
})
.catch(err => {
console.log(err)
});
};
const uploadLookup = function uploadLookup() {
form.append("Content-Type", "application/octect-stream");
form.append('file', buffer2);
fetch(url2, {method: 'PUT', headers: headers, body: form})
.then(data => {
console.log(data)
})
.catch(err => {
console.log(err)
});
};
if (!apiName !== true) {
uploadAPI()
} else {}
if (!lookupName !== true) {
console.log("Uploading Lookup File");
uploadLookup()
} else {}
I tried using a "setTimeout" function which does not seem to work as I would have liked it to. My best guess is each API call would need to be it's own separate socket connection? Any help with getting me in the right direction is appreciated.

Promise.all([
fetch(url),
fetch(url2)
]).then(function (res) {
// Get a JSON object from each of the responses
return res.json();
}).then(function (data) {
// do something with both sets of data here
console.log(data);
}).catch(function (error) {
// if there's an error, log it
});

How to authenticate using bearer token using got.js

I'm trying to switch from request.js to got.js. I expect to see the got.js implementation authenticate similarly to how the request.js library does. But, instead, I get the following error.
auth no longer supported. Replaced by username and password.
There is no mention of bearer tokens on the docs page.
So how do I authenticate my request using bearer tokens using got.js? Or what am I doing wrong?
Current code: request.js, working
const request = require('request');
const module.exports = config => {
const options = {
auth: {
bearer: config.secret,
},
};
const result = await new Promise(( resolve, reject, ) => {
request.get( url, options, ( error, response, body, ) => {
...
New code: got.js, throws error
const got = require('got');
module.exports = async config => {
const options = {
auth: {
bearer: config.secret,
},
};
const result = await got(url, options);
...
}

This should be worked, if I'm not wrong
let token = 'your token'
const options = {
headers: {
'Authorization': `Bearer ${token}`
}
};

worked for me !!
router.get('/product', (req,res)=>{
const dataStream = got.stream({
url: "http://localhost:8000/products",
method: "GET",
hooks: {
beforeRequest: [
options => {
var token= 'Bearer ' + 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpYXQiOjE2MTkzODA0NjIsImV4cCI6MTYxOTM4NDA2Mn0.JoJbRpPniGuMbwULEtts7I19QxEImvarT6AoqVuNb9w'
options.headers['Authorization'] = token;
}
]
}
});
pipeline(dataStream, res, (err) => {
if (err) {
console.log(err);
res.sendStatus(500);
}
});
});
