Microsoft Teams扩展隐身窗口SSO认证错误排查求助

我正在使用React.js和C#开发Microsoft Teams扩展，该扩展采用SSO认证机制。在Google Chrome隐身窗口测试时，SSO令牌获取过程持续出现错误，但通过admin.teams.microsoft.com访问应用时无此问题。

复现步骤 #

• 打开Google Chrome隐身窗口，访问https://dev.teams.microsoft.com/
• 登录Microsoft Teams开发者平台UI
• 使用提供的压缩包导入扩展
• 尝试启动应用，在开发者控制台查看SSO相关错误

错误信息 #

• POST https://login.microsoftonline.com 返回400 Bad Request
• POST https://cc-frontline-backend.azurewebsites.net 返回401 Unauthorized
• Error in getAccessToken: "Exchange SSO ID Token failed with HTTP status 401"
• Error in useEffect: "Failed to retrieve access token: invalid_token"
• 错误截图显示Microsoft Teams响应错误

代码片段 #

function initializeTeamsSdk(): Promise<void> {
    return new Promise((resolve, reject) => {
        microsoftTeams.initialize(() => {
            console.log("Teams SDK initialized successfully.");
            resolve();
        });
    });
}

async function AuthenticateWithSSO(): Promise<IAccessTokenRequestBody> {
    await initializeTeamsSdk(); 
    return new Promise((resolve, reject) => {
        microsoftTeams.authentication.getAuthToken({
            successCallback: (token: string) => {
                try{
                    const decoded = jwtDecode(token);
                    const requestBody = {
                        tenantId: decoded.tid,
                        ssoToken: token,
                        clientId: decoded.aud,
                    };

                    SetClientId(requestBody.clientId);
                    SetSsoToken(requestBody.ssoToken);
                    SetTenantId(requestBody.tenantId);

                    microsoftTeams.appInitialization.notifySuccess();
                    resolve(requestBody);
                }catch(error){
                    reject("Token decoding failed");
                }
            },
            failureCallback: (error: string) => {
                microsoftTeams.appInitialization.notifyFailure({
                    reason: microsoftTeams.appInitialization.FailedReason.AuthFailed,
                    message: error,
                });
                    reject(error);
            },
            resources: [process.env.SSO_TAB_APP_URI as string],
        });
    });
}
