我正在使用Prepackaged Identity Server 5.0配置 WSO2 API Manager 1.10 .

已按照https://docs.wso2.com/display/CLUSTER44x/Configuring+the+Identity+Server+5.1.0+as+a+Key+Manager+with+API+Manager+1.10.0中的所有步骤操作 .

我能够使用Identity server和 API Manager 执行 SSO . 我能够使用Identity server生成API令牌 .

当我尝试重新生成它失败并出现错误 - 令牌撤销失败:HTTP错误代码:400

以下是身份服务器的日志
