SyntaxError: Invalid or unexpected token

matthieuEv commented 10 months ago

I was working on a project, when suddently, ytdl-core stoped working. So i created a new project to try a simple code:

const fs = require('fs');
const ytdl = require('ytdl-core');

const url = 'https://www.youtube.com/watch?v=dQw4w9WgXcQ';

ytdl(url)
  .pipe(fs.createWriteStream('video.mp4'));

I have the latest package of ytdl: ytdl-core@4.11.5

But when i run the code: node index.js, i get the error:

evalmachine.<anonymous>:426
koa=function(a,b,c,d){var e=null;switch(b){case "JSON":try{var f=c.responseText}catch(h){throw d=Error("Error reading responseText"),d.params=a,JB(d),h;}a=c.getResponseHeader("Content-Type")||"";f&&0<=a.indexOf("json")&&(")]};gma(ncode);
                                                                                                                                                                                                                             ^^^^^^^^^^^^^^^^

I'm not sure what appened, but it was working just fine, and suddently, this appear out of knowhere, without modifying anything.

I'm getting the same error in my project without changing anything. Presumably YouTube changed something up, but I certainly didn't expect that to produce an error like this!

ftrbnd commented 10 months ago

Yeah I also just started getting this error today. My app was working fine yesterday, and one of my users just notified me that one my features that uses ytdl-core wasn't working. Hope it gets fixed soon!

akrom123 commented 10 months ago

I have the same error :(

avallois commented 10 months ago

Same ! Showing like this for me:

evalmachine.<anonymous>:426
koa=function(a,b,c,d){var e=null;switch(b){case "JSON":try{var f=c.responseText}catch(h){throw d=Error("Error reading responseText"),d.params=a,JB(d),h;}a=c.getResponseHeader("Content-Type")||"";f&&0<=a.indexOf("json")&&(")]};gma(ncode);

Exorcismus commented 10 months ago

as a quick investigation, I beleive the error is related to funcion extractNCode in sig.js

oa=function(a,b,c,d){var e=null;switch(b){case "JSON":try{var f=c.responseText}catch(h){throw d=Error("Error reading responseText"),d.params=a,JB(d),h;}a=c.getResponseHeader("Content-Type")||"";f&&0<=a.indexOf("json")&&(")]}'\n"===f.substring(0,5)&&(f=f.substring(5)),e=JSON.parse(f));break;case "XML":if(a=(a=c.responseXML)?moa(a):null)e={},g.cc(a.getElementsByTagName("*"),function(h){e[h.tagName]=noa(h)})}d&&ooa(e);

is being mis-parsed

could be related to function utils.cutAfterJS failing to parse (")]}'\n"===f.substring(0,5)&&(f=f.substring(5)),e=JSON.parse(f))

Try it. Work for me.

duykhanh09103 commented 10 months ago

+1 i got it today too without changing any of the code

timfong888 commented 10 months ago

I got a similar error without changing any code as well:

Seeing this issue as well without any changes to code.
