MSAL js、AAD B2C 多重身份验证、400 错误请求、请求 header 太长

Question

MSAL js 版本：v0.2.4；
Chrome 版本：79.0.3945.88（正式版）（64 位）

从各种post了解到，由于cookie堆积，我们看到'400 Bad Request - Request header too long'，但事实并非如此发生在我所有的开发环境中。我想知道，为什么它不在本地环境中（运行来自 VS Code），而是在已部署的环境中（Azure App Service）
我可以将 MSAL 包更新到最新版本，但同时以前它在部署的环境中工作正常但现在不行，为什么？
范围错误消息 (AADB2C90055) 与 'Bad Request - Request header too long' 有任何联系吗？

AADB2C90055: The scope 'openid profile' must specify resource

任何类型的信息都会对我或其他人有用，在此先感谢

这是我的应用程序中使用的代码，

let userAgentApplication: Msal.UserAgentApplication;

const createAuthorityUrl = (tenantId: string, policy: string) => {
  return `https://${tenantId}.b2clogin.com/tfp/${tenantId}.onmicrosoft.com/${policy}`;
};

export const b2cLogin = (config: B2CConfig) => {
  const msalAppConfig = {
    cacheLocation: 'localStorage',
    redirectUri: `${location.protocol}//${location.host}`,
    navigateToLoginRequestUrl: false,
    storeAuthStateInCookie: true,
    validateAuthority: false,
  };

  const { clientId, tenantId, myb2cSigninPolicy, myb2cPasswordResetPolicy } = config;

  return new Promise(resolve => {
    let handlingPasswordReset = false;
    const app = new Msal.UserAgentApplication(
      clientId,
      createAuthorityUrl(tenantId, myb2cSigninPolicy),
      (errorDesc: string, token: string) => {
        if (errorDesc && errorDesc.indexOf('AADB2C90118') > -1) {
          // user forgot password
          // https://github.com/Azure-Samples/active-directory-b2c-javascript-msal-singlepageapp/issues/9#issuecomment-347556074
          handlingPasswordReset = true;
          new Msal.UserAgentApplication(
            clientId,
            createAuthorityUrl(tenantId, myb2cPasswordResetPolicy),
            () => null,
            msalAppConfig,
          ).loginRedirect();
        }        
        return resolve(token);
      },
      msalAppConfig,
    );

    if (!handlingPasswordReset) {
      userAgentApplication = app;
    }


    // Seems that MSAL's acquireTokenSilent() won't resolve if run within an iframe
    if (window.parent !== window) {
      return resolve('');
    }
    if (!userAgentApplication.isCallback(location.hash)) resolve(getAccessToken());    
  });
};

export const getAccessToken = async (): Promise<string> => {  
  if (!userAgentApplication) {
    throw new Error('getAccessToken attempted before authentication initialized');
  }
  try {
    return await userAgentApplication.acquireTokenSilent(['openid']);
  } catch (error) {
    console.log(error);
    return '';
  }
};

错误 HTTP 400: Size of header request is too long 通常是因为cookies太多或cookies太大.
