SyntaxError: Unexpected token - Getting error in Ubantu (16.04)

[Topiya]

I am using v5.1.2 version of @ybd-project/ytdl-core which is working fine in Windows but getting below error Ubantu. Node version is same in both systems as mentioned below.

• @ybd-project/ytdl-core version: v5.1.2
• Node.js version: 20.17.0
• Operating system: Ubantu (16.04)

/@ybd-project/ytdl-core/package/YtdlCore.js:68
    options ??= {};
             ^
SyntaxError: Unexpected token ?

Can anyone please help me solve this problem?

[ybd-project]

Thank you for your report. I will install Ubuntu on the virtual machine and try it.

[Topiya]

Thank you. I'd appreciate it if you could reply soon, as I need the solution urgently.

[ybd-project]

It works fine in my environment. Please let me know what code you are implementing as best you can.

[Topiya]

Ubantu verion: 16.04

const YtdlCore = require("@ybd-project/ytdl-core");

app.get('/ybdtest', async function (req, res) {
 const fs = require('fs');
 const ytdl = new YtdlCore({});
  // Download a video
 ytdl.download('https://www.youtube.com/watch?v=aqz-KE-bpKQ').pipe(fs.createWriteStream('video.mp4'));
});

[Topiya]

Also I would like to mention that I am getting above error on run the script 'node download.js', without even accessing route.

[ybd-project]

const YtdlCore = require("@ybd-project/ytdl-core");

but change it to the following

const { YtdlCore } = require("@ybd-project/ytdl-core");

[Topiya]

I have tried with both of it but getting same error.

So I have tried lower version of @ybd-project/ytdl-core 5.0.7 with node 14.21.3 using const YtdlCore = require("@ybd-project/ytdl-core"); which is also giving same error.

[ybd-project]

Maybe the problem is the "??=" syntax (if the value is empty, assign it). So we will release a version (v5.1.3) by the end of tomorrow that does not use this syntax.

[ybd-project]

v5.1.3 has been released. Please check to see if the problem has been fixed.

[Topiya]

Using latest plugin v5.1.3, I have checked with node 20.17 in Ubantu (16.04) . Still getting same error.

I am using the same Ubuntu version with node 14 and ybd-project/ytdl-core 5.1.3 and i am experiencing the same error. Is there a compatible version for node 14?

[ybd-project]

Since the “??=” was still there, we removed it all and released v5.1.4.

The "??=" syntax in question was supported starting with Node.js 16, so I believe the error occurs in 14. I think it is ok since we removed "??=" completely in v5.1.4.

I am getting below error on accessing my node route.

at async Function.generatePoToken (/home/ubuntu/api/node_modules/@ybd-project/ytdl-core/package/core/PoToken.js:8:26)
(node:7840) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection,

Below is my node GET route code:

const { YtdlCore } = require("@ybd-project/ytdl-core");

app.get('/ybdtest', async function (req, res) {   // I have tried here by removing async also
  const fs = require('fs');
  const ytdl = new YtdlCore({});
  ytdl.download('https://www.youtube.com/watch?v=aqz-KE-bpKQ').pipe(fs.createWriteStream('video.mp4'));
});

[ybd-project]

It seems to be due to the fact that error handling is not set up when poToken generation fails. A version (v5.1.4-2) fixing this will be released soon.

I am experiencing the same PoToken error. We are eagerly awaiting your new fixes.

[ybd-project]

Released. We are currently building an environment with Ubuntu 16.04 and Node.js 14 and 20.

Getting the following error after updating the new release.

[ybd-project]

The best option is to update Node.js, but if you can't, specify PoToken and VisitorData in the options.

[ybd-project]

Is the problem resolved?

[Neelam1990]

Not yet, so we are planning to update ubuntu as well as node js.
