SyntaxError: Invalid or unexpected token

matthieuEv commented 1 year 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);
                                                                                                                                                                                                                             ^^^^^^^^^^^^^^^^

Node.js v18.17.1

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 1 year 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 1 year ago

I have the same error :(

avallois commented 1 year 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 1 year 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))

Seeing this issue as well without any changes to code.
