faced same issue just a today. It was working fine a week before

[ImBackJWick]

I'm facing the same issue and there is no button appearing on the extension to download the course or videos. please provide the solution soon for this.

Same here issue here -

The extension attempts to connect to a native messaging host (com.cristminix.llfetcher) using Chrome's native messaging API
Native Messaging Host manifest is missing -
Service Worker loader.js points to " import './assets/background.js-YocnhhG8.js " which on line 34 states the constant of com.cristminix.llfetcher, which is the host.

A failure in this connection logs the error Failed to connect.
Error Handling

The function z() is responsible for logging connection errors.
The error likely occurs because the native host manifest or executable is not properly installed.

The native messaging host requires a JSON manifest file that specifies:
"name": "com.cristminix.llfetcher"
"path" to the executable that handles messages.
"allowed_origins" including the extension's ID.
Localhost Services

The extension uses localhost endpoints (e.g., 127.0.0.1:5000) for certain operations, but these are separate from the native messaging host.

The manifest should look like:
{
"name": "com.cristminix.llfetcher",
"description": "Native Messaging Host for LLFetcher",
"path": "/absolute/path/to/executable",
"type": "stdio",
"allowed_origins": [
"chrome-extension://ochphockkknjbngniadiocnbgpbmpekc/"
]
}

I did find that a manifest with these config details can be found within the main LLFetcher-man, however I am unable to get this to work, the exe is also found within that folder - "\LLFetcher-main\native-messaging\node\llfetcher-native.exe"

\LLFetcher-main\LLFetcher-main\native-messaging\node\mainifest.json

{
"name": "com.cristminix.llfetcher",
"description": "LLFetcher is stand for LinkedIn Learning Fetcher",
"path": "E:\projects\LLFetcher\native-messaging\node\llfetcher-native.exe",
"type": "stdio",
"allowed_origins": [
"chrome-extension://ncfdbofhgnoammldlfcfdkcldpbepjhc/"
]
}
