"MissingAuthError: Add a "api_key" or a .har file" ERROR EVEN IF "a.har" FILE IS PRESENT

I've logged inside https://chatgpt.com/ and followed your steps but it doesn't seem to detect the file, resulting it to switch to LiaoBots provider. Should I extract the .har file with a specific browser? Currently using Thorium Browser.

UPDATE: Tried to download a .har file with Firefox and Chrome, same issue.
