I am trying to login using JWT token issued by External JWT Provider. When I use Reconcile API I got 500 error with following stack trace:

Here is my decoded JWT payload:
{
"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” in provider config is set to “email”. I tried setting it to “user_name” too, but it does nothing. Looks like it searches for “null” claim at io.fusionauth.jwt.domain.JWT.lookupClaim(JWT.java:416) but I have no idea when and how could it pass null there, when the token has all fields filled. Any suggestions?
EDIT:
UPDATE: I tried to make it work and I noticed that it works in specific case. Here is part of the code:
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;
When I debug on line
LoginResponse response = lambdaDelegate.execute(x -> x.reconcileJWT(request));
and wait a while, it works. There is no error, user is registered and logged in FusionAuth in my application and I am authorized in endpoints when I use returned token. Still trying to figure out why works when I debug on that line and wait.
