Legendary isn't authenticating

[Anastazbnko]

Platform

Operating system and version: Fedora Linux 38
Legendary version (legendary -V): 0.20.33, "Undue Alarm", installed via DNF

Expected Behavior

Legendary successfully authenticates

Current Behavior

Legendary throws an error: (output of legendary -v auth)
[cli] INFO: Testing existing login data if present...
[WebViewHelper] DEBUG: Webview unavailable, disabling webview login (Exception: ModuleNotFoundError("No module named 'webview'")).
Please login via the epic web login!
If the web page did not open automatically, please manually open the following URL: https://legendary.gl/epiclogin
Please enter the "authorizationCode" value from the JSON response: <redacted>
[Core] ERROR: Logging in failed with JSONDecodeError('Expecting value: line 1 column 1 (char 0)'), please try again.
[cli] ERROR: Login attempt failed, please see log for details.

• Note - I have tried running with --disable-webview, results are the same

Steps to Reproduce

1. Run legendary auth
2. Legendary throws an error and authentication fails

Additional information

This first popped up when I tried list-games, while I was still supposed to be authenticated. I proceeded to clear my user.json and try to login again, which didn't work so I opened this issue.

I am also having this issue. I haven't touched my legendary instance since 0.20.31. I replaced the exe with 0.20.33.

I have what's probably a variation of this problem. In my case, it's impossible to authenticate with 0.20.33, as the webview window never appears. Instead, the program just hangs indefinitely when it would. I went back to 0.20.32 to authenticate and had no trouble.

Just fixed it, i got that error because my home network using private vpn. Epic detected it as bot and require me to solve their captcha.
legendary doesn't forward captcha header, so that's why i get null result and json decode error.
Just whitelist ol.epicgames.com in your router for prevent route in vpn, and everything will be working
