描述

Hi,

some users are experiencing this error when using Chrome. Hellojs is working with AzureB2C and it works ok.

HTTP Error 400. The size of the request headers is too long.

This is the exception when trying to execute hello.login() which happens in chrome in some cases.

It works when we switch to incognito or use other browser.

Is this something related to the session or theres some other issue? I've tried removing cookies, clearing local storage.

研究方向
Investigate why Chrome sends overly large request headers during hello.login() with Azure B2C. Compare headers in normal vs incognito mode. Check if cookies or local storage data is being appended to request headers. Look at hello.js source code (src/) for how OAuth2 redirects and token exchanges are constructed. Reproduce with a simple test case focusing on Azure B2C endpoints.
