SyntaxError: Missing catch or finally after try

Same issue here. It happens but not every time.

Edit : You can use 4.10.0, it works but is kinda slow.

I have the same issue :
evalmachine.:24
c[74]),c[64])((0,c[25])(c[24],c[41]),c[35],c[33+Math.pow(8,3)%229],c[92]),c[70])(c[87],c[27])}try{8>=c[92]&&(0,c[15])((0,c[35])(c[36],c[20]),c[11],c[29])}catch(d){(0,c[60])(c[92],c[93])}try{1>c[45]?((0,c[60])(c[2],c[93]),c[60])(c[91],c[93]):((0,c[88])(c[93],c[86]),c[11])(c[57])}catch(d){(0,c[85])((0,c[80])(),c[56],c[0])}};qma(ncode);

provisionally im using https://www.npmjs.com/package/@distube/ytdl-core work for me

Try this:

Happened a few hours ago a few times, then it worked again, now it's broken again

provisionally im using https://www.npmjs.com/package/@distube/ytdl-core work for me

Try this: "ytdl-core": "npm:@distube/ytdl-core",

Don't forget to add the version number ^4.11.9

"ytdl-core": "npm:@distube/ytdl-core@^4.11.9"

this exact error was 2 weeks ago in 4.11.3 and then we freaked out, and then they fixed and now it is back again, it is probably because youtube keep changing their code so...

This fork uses some custom HTTP client that doesn't play ball when you mock fetch in tests: https://www.npmjs.com/package/undici

It works in practice but it ruins all my test suites.

After some research I've found that the problem has to do with the signature deciphering extraction of functions, specifically the extractNCode function, when calling cutAfterJS it fails to escape the following string /[/,-33,/,/]{/,function due to the literal / characters inside a RegEx character set, and so it counts opening and closing brackets incorrectly as it treats most part of the code as a regular expression, resulting in the script not getting to the end of the function and missing a catch block and a return statement.

TEMP FIX
Add a check for RegEx character sets, replace

node-ytdl-core/lib/utils.js

Lines 97 to 102 in 0d3f91b

	// Go through all characters from the start
	for (i = 0; i < mixedJson.length; i++) {
	// End of current escaped object
	if (!isEscaped && isEscapedObject !== null && mixedJson[i] === isEscapedObject.end) {
	isEscapedObject = null;
	continue;

with

  // Go through all characters from the start
  for (i = 0; i < mixedJson.length; i++) {
    // End of current escaped object
    if (!isEscaped && isEscapedObject !== null && mixedJson[i] === isEscapedObject.end) {
      // Ignore character inside RegEx character set with a range of 30 characters
      let charsetStart = mixedJson.substring(i - 15, i).search(/\[[^\]]*/)
      let charsetEnd = mixedJson.substring(i, i + 15).search(/[^\[]*\]/)
      if (mixedJson[i] == '/' && charsetStart !== -1 && charsetEnd !== -1)

4.11.9 cannot play some streams, I updated to 4.11.10 and it's working normally

npm i ytdl-core@npm:@distube/ytdl-core@latest
