Netflix subtitles and language tracks stuck on “Loading…” in Chrome. Console shows TypeError in pageScript_lln.min.js

[Paul_Lastname]

Hi,

Language Reactor was working perfectly with Netflix for several days, but today it suddenly stopped loading subtitles and language tracks.

Environment:

• Browser: Google Chrome
• Platform: macOS
• Extension: Language Reactor Chrome extension
• Region/Country: Bulgaria
• Netflix subtitles work normally in Firefox without Language Reactor
• I have an active Pro trial

What happens:

• Language Reactor opens on Netflix

• The settings panel shows:

  • Original language: Loading…
  • Netflix audio language: Loading…
  • Netflix subtitle language: Loading…

• Subtitles do not load inside Language Reactor

• Netflix itself still works correctly

• Subtitles are available when I open Netflix in Firefox without Language Reactor

Example Netflix video where this previously worked and now stopped working:
https://www.netflix.com/watch/81720203

Language configuration:

• Netflix audio: English
• Netflix subtitles: English
• Translation language: Russian

What I already tried:

• Restarted Chrome completely
• Tried Incognito mode
• Disabled all other Chrome extensions
• Cleared ALL Chrome browsing data and cache for all time
• Reopened Netflix
• The problem still happens

Console errors:

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'b')

    at Tt (pageScript_lln.min.js:8987:93499)

Also seeing:

[LR:MSG] Auth state changed
[LR:MSG] refreshUserData: got result: {status: 'success', licenseStatus: 'TRIAL'}

So the extension seems to authenticate correctly, but then crashes while trying to initialize Netflix subtitles/language tracks.

I am attaching screenshots of:

• the LR settings panel showing endless “Loading…”
• Chrome console errors

Hello,

I don’t speak well english so excuse me If i don’t express myself correctly.

I have same sort of problem, the language reactor products a lot of bugs, furthermore it seems that a lot a problem started a few day after I installed another extension called fluentai that I use for disney+ but I am not sure.
So, even I hover a word using the fluentai extension I see a tooltip about language reactor like you can see in the picture below lol.

[Paul_Lastname]

I think you should try one thing at a time. In Chrome, you can disable and enable extensions individually.

[Belka_Hayawen]

I tried a lot of things which did not work :

• disable other extensions.
• use different version of chrome browser
• check for updates.
• …

did you solve your problem?

This is what I get in the dev console :

@Belka_Hayawen
I’ve already tried all of those, but unfortunately nothing seems to help.
I’m glad I didn’t subscribe, because it broke during the trial period.

[Yana]

@Belka_Hayawen Could you help us by pasting this code into the console and let me know the version that appears there:

netflix.reactContext.models.playerModel.data.config.core.initParams.version

[Belka_Hayawen]

hi,
here you are :
0.3309.0

[Paul_Lastname]

@Yana,
btw I’ve just checked and this issue disappeared for me. Now I see subtitles are loaded.

For me the value of netflix.reactContext.models.playerModel.data.config.core.initParams.version is 0.3311.0
