The webRequest.onAuthRequired API fails to authenticate proxy in MV3

[Dhanur Sehgal]

Hi all!

It seems like the webRequest.onAuthRequired API is malfunctioning due to some reason in MV3.

It is a simple web proxy extension, but authentication is returning status 407 (Proxy Authentication Required).

I have tested the proxy server manually and using a proxy switcher extension - the proxy server is working fine.

Here is the code for reference:

Bk script:

chrome.webRequest.onAuthRequired.addListener
(
    function(details, callbackFn)
    {
      return {
        authCredentials: {
          username: "xyz",
          password: " xyz  "
        }
      };
    },
    {
        urls: [
            "<all_urls>"
        ]
    },
    ["asyncBlocking"]
);

-------------------------------------------------------------

Manifest:

    "permissions":
    [
        "proxy",
        "storage",
        "webRequest",
        "webRequestAuthProvider",
        "background"
    ],
    "host_permissions": ["<all_urls>"],

-------------------------------------------------------------

Please help, I'd be very grateful

Thanks in advance =)

Hi Dhanur,

It sounds like you are hitting this bug. Do you agree, or am I misunderstanding?

Hi Patrick

Yes, the onAuthRequired event is not getting fired. (I tried logging)

Best,

Hi Patrick

I see that the bug has been fixed.

I wanted to know the lowest Chrome release version containing the patch.

How can I know that?

Best,

Hi Dhanur!

Chrome 123.0.6263.0 is when the fix landed.
