我正在尝试使用外部 JWT 提供者颁发的 JWT 令牌登录。当我使用 Reconcile API 时，出现以下堆栈跟踪的 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"
}
提供者配置中的“uniqueIdentityClaim”设置为“电子邮件”。我也尝试将其设置为“user_name”，但它什么也没做。看起来它在 io.fusionauth.jwt.domain.JWT.lookupClaim(JWT.java:416) 搜索“null”声明，但我不知道当令牌已填充所有字段时它何时以及如何传递 null。有什么建议么？
编辑：
更新：我试图让它工作，我注意到它在特定情况下工作。以下是部分代码：
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));
稍等片刻，它起作用了。没有错误，用户在我的应用程序中注册并登录了 FusionAuth，当我使用返回的令牌时，我在端点中获得了授权。当我在那条线上调试并等待时，仍然试图弄清楚为什么会起作用。
