我正在尝试使用由外部JWT Provider发行的JWT令牌登录。 当我使用协调API时，出现以下堆栈跟踪信息，出现500错误：

这是我解码的JWT有效负载：
{
"user_name": "name.surname",
"scope": [
"read"
],
"exp": 1566331043,
"applicationId": "37cf7a75-6b3a-49d9-99d9-6f261c4f6851",
"jti": "eddc15b6-f479-47c0-8d08-8b9aacf6dbe8",
"email": "name.surname@domain.pl",
"client_id": "37cf7a75-6b3a-49d9-99d9-6f261c4f6851"
}
“ uniqueIdentityClaim”设置为“电子邮件”。我也尝试将其设置为“ user_name”，但是它什么也没做。 看起来它在io.fusionauth.jwt.domain.JWT.lookupClaim（JWT.java:416）上搜索“空”声明，但是当令牌已填充所有字段时，我不知道何时以及如何在其中传递null。有什么建议吗？
编辑：
更新： 我试图使其工作，但我发现它在特定情况下可以工作。这是代码的一部分：
UUID appId = fusionAuthConfig.getApplication().id;
LookupResponse lookupResponse = lambdaDelegate.execute(x -> x.lookupIdentityProvider("domain.pl"));
IdentityProviderLoginRequest request = new IdentityProviderLoginRequest();
request.identityProviderId = lookupResponse.identityProvider.id;
request.applicationId = appId;
request.setEncodedJWT(token);
LoginResponse response = lambdaDelegate.execute(x -> x.reconcileJWT(request));
return response;
当我在线调试时
LoginResponse response = lambdaDelegate.execute(x -> x.reconcileJWT(request));
，请稍等片刻。没有错误，用户已在我的应用程序中的FusionAuth中注册和登录，并且在使用返回的令牌时获得了端点的授权。 仍在尝试找出为什么能在我调试该行并等待时起作用。
答案 0 :(得分：0)
我设法解决了。问题出在使用lambdaDelegate。当我删除 '''
LookupResponse lookupResponse = lambdaDelegate.execute(x -> x.lookupIdentityProvider("domain.pl"));
''' 有效。我只需要传递identifyProviderUuid，而不是查找它。当从FusionAuth的2个方法一个接一个地调用而第一个方法还没有完成时，似乎存在某种冲突
