FetchError: "Forbidden" Response from Pluralsight API During Video Metadata Retrieval

[bilalelmahdaoui]

I am encountering a FetchError when attempting to download courses using the Pluralsight scraper. Specifically, the error occurs while fetching video metadata from the endpoint https://app.pluralsight.com/video/clips/v3/viewclip. The error message indicates an "invalid JSON response body" with the reason: "Forbidden".

Steps to Reproduce:

Run the command:
npm run get -- "https://app.pluralsight.com/library/courses/rust-fundamentals/table-of-contents"

Observe the error in the logs.

Logs:

Downloading course: rust-fundamentals
Retrieving metadata for: 1. Course Overview
FetchError: invalid json response body at https://app.pluralsight.com/video/clips/v3/viewclip reason: Unexpected token 'F', "Forbidden" is not valid JSON
    at /path/to/node_modules/node-fetch/lib/index.js:273:32
    ...
    at async getVideoUrl (/path/to/script.js:17:20)

Expected Behavior:

The scraper should fetch the metadata and download the course videos successfully.

Actual Behavior:

The fetch request to the API endpoint returns a 403 Forbidden response, preventing further execution.
