To disable CORS for file:// errrors in chrome follow the steps below.

NOTE: These steps are for Unbuntu OS

  1. Make sure your chrome browser is closed.
  2. Open terminal and run the following command google-chrome --disable-web-security --user-data-dir
  3. Remember that disabling CORS can expose your browser to security risks, so it's essential to revert these changes after testing:
    • Close the Chrome instance that was launched with CORS disabled.
    • Open Chrome normally (without any special flags) for regular browsing.

CAUTION: This change disables CORS restrictions for local file access, but it's not recommended for general browsing due to security implications.
