Since 1 or 2 hours, all videos passed on ytdl-core return this "Invalid regular expression" error

I'm having the same problem as well. Receiving the same error as above. Everything worked fine yesterday.

cchen028 · 2022-08-18T00:16:41Z

Experiencing same issue, getting identical stack trace as well.

MohamedMontasser03 · 2022-08-18T00:46:07Z

Okay I am trying to figure out the problem but this is my first time working with the source code of this project and with the youtube cipher algorithm so it's taking a while anyways I've narrowed the problem down to a problem with evaluating nTransformScript because the code returned from youtube is for some reason broken, that's the conclusion I reached

TaylorDuck72 · 2022-08-18T00:57:17Z

Still having same problem

austinharms · 2022-08-18T01:09:25Z

this solved it for me
#1108 (comment)

Hakunek · 2022-08-18T01:13:20Z

If you need to use it rn and don't want to/can't tinker inside module
downgrade to version 4.10.0
npm command:
npm i ytld-core@4.10.0
only versions 4.10.1+ gave me this error during testing

austinharms · 2022-08-18T01:15:52Z

~~I also had the issue on version 4.10.0, and 4.9.? (I can't remember the last digit)~~
apparently I screwed up the downgrade when testing the different versions

MohamedMontasser03 · 2022-08-18T01:18:19Z

this solved it for me #1108 (comment)

Not sure if that's the proper solution or not but it does work

MidSpike · 2022-08-18T01:49:44Z

Can reproduce: with almost all videos that I test with:

dskaiser82 · 2022-08-18T05:36:39Z

@austinharms
I went into package.json changed the version to
"ytdl-core": "4.10.0"

deleted my node modules
and ran yarn (yarn for me)

I'm back!

Holy shit I was about to wipe my system because this week I had some pc malware issues I solved. But when in doubt CHECK the GITHUB! I was that close....thanks to everyone for the comments...

I skew front-end but hoping devs solve the issue!

dskaiser82 · 2022-08-18T05:39:49Z

But if we know 4.10.0 works, then we know that the PR that came after introduced a bug....so whats the PR for 4.10.1?

dskaiser82 · 2022-08-18T05:49:11Z

@dsnsgithub on 4.10.0 its slow but downloading but will test audio when its up

dsnsgithub · 2022-08-18T05:52:36Z

@dskaiser82 Thank you, your fix works. ytdl-core@4.10.0 seems to be working while ytdl-core@4.11.0 seems to have a problem with dependences.

dskaiser82 · 2022-08-18T06:05:18Z

@dsnsgithub Good! Yean I have audio working fine too on the video below....but did take a longer than normal....I want to test another vid to see if speeds can be faster....but for now I'll take this band aid fix

https://www.youtube.com/watch?v=moiS5zDIuPM

dskaiser82 · 2022-08-18T06:09:13Z

Yeah I think this version is slower than before, but I do like to do highest Audio, Highest Video

gatecrasher777 · 2022-08-18T06:43:19Z

Last week it was closing braces in strings. To confuse parsers.
This week YouTube have thrown some regex into their code spaghetti.

WaqasIbrahim · 2022-08-18T11:12:47Z

Can anyone please attach base.js file that has this issue because I can't reproduce this on my end.

gatecrasher777 · 2022-08-18T11:48:57Z

@WaqasIbrahim sent via email

danielsss · 2022-08-18T11:51:45Z

I've got the same issue +1

gatecrasher777 · 2022-08-18T12:10:44Z

Needs exports.cutAfterJSON in util.js to skip over regex.

When it encounters

/,,[/,913,/](,)}/

as an array value in base.js it sees the } as the end of the n code function that is being parsed. So evaluation breaks.

WaqasIbrahim · 2022-08-18T12:41:09Z

I just tested ncode extraction on a file @gatecrasher777 sent. The solution I suggested in the closed issue: #1108 (comment) still works.

arinmodi · 2022-08-18T14:57:50Z

downgrading the version decreases the singnificat download spped, how can i solve that ?

CuteSkyler · 2022-08-18T17:32:34Z

For some reason, I kept getting HTTPError [FetchError]: request to https://discord.com/api/v7/channels/[channelid]/messages failed, reason: read ECONNRESET in the new update, if it is of any help. Downgrading to ytdl-core@4.10.0 fixed it for me.

dskaiser82 · 2022-08-18T19:13:49Z

@arinmodi Thats the state I chose, degraded version but MUCH slower download speeds.....no PR's in yet for the fix right?

GreepTheSheep · 2022-08-18T19:16:48Z

Made a fork of the temporary fix here: https://github.com/GreepTheSheep/node-ytdl-core

You can add it on your package.json with npm npm i ytdl-core@https://github.com/GreepTheSheep/node-ytdl-core

dskaiser82 · 2022-08-18T19:23:40Z

@GreepTheSheep
Good stuff!
I took the fix one step further and did a Pull Request so we can get this fix in.

Wanted to add that this can too be fixed by downgrading to 4.10.0

gatecrasher777 · 2022-08-20T10:28:08Z

Downgrading to 4.10.0 will mean the N transform gracefully fails. Everything will work, but downloads will be throttled.
