我使用this文档在远程IdP解决方案中使用SAML配置SSO但是当我尝试访问存储或发布主页时，我在导航器上收到HTTP 500错误并出现以下错误在服务器日志上：

以下是我正在使用的site.json配置示例：
"ssoConfiguration" : {
"enabled" : "true",
"issuer" : "wso2am-sp",
"identityProviderURL" : "https://sps-hom.sample.com/affwebservices/public/saml2sso",
"keyStorePassword" : "wso2carbon",
"identityAlias" : "sps",
"responseSigningEnabled":"true",
"assertionSigningEnabled":"true",
"keyStoreName" :"/opt/wso2am-2.0.0/repository/resources/security/wso2carbon.jks",
"passive" : "true",
"idpInit" : "true",
"idpInitSSOURL" : "https://sps-hom.sample.com/affwebservices/public/saml2sso?SPID=wso2am-sp",
"externalLogoutPage" : "https://sps-hom.sample.com/affwebservices/public/saml2sso?slo=true",
"signRequests" : "true",
},
我可以看到第一跳中从SP到IdP的SAMLRequest，然后我可以看到从IdP到SP的SAMLResponse，但我不知道导致问题的原因以及如何解决它。
有人可以帮我理解发生了什么吗？
感谢。
