Unable to partial import existing users

Getting advice
1

Hey there,

I am trying to import existing users which i exported from Auth0, i have JSON file like this which i copied the structure from the mailing list of Keycloak.

{
    "realm": "production",
    "users": [
        {
            "emailVerified": true,
            "firstName": "John",
            "lastName": "Doe",
            "email": "johndoe@gmail.com",
            "federatedIdentities": [
                {
                    "identityProvider": "google-oauth2",
                    "userId": "1232313132132313123"
                }
            ]
        },
        {
            "emailVerified": true,
            "firstName": "John",
            "lastName": "Doe",
            "email": "john@doe.org",
            "federatedIdentities": [
                {
                    "identityProvider": "google-oauth2",
                    "userId": "111111111111111111111"
                }
            ]
        },
        {
            "emailVerified": true,
            "firstName": "Doe",
            "lastName": "John",
            "email": "john@doe.org",
            "federatedIdentities": [
                {
                    "identityProvider": "google-oauth2",
                    "userId": "123182813218338173179189"
                }
            ]
        }
      ]
  }

I’m stuck right now, when i try to import it, i keep getting status code 500 and a empty JSON as a response, also no luck from the server logs. Any suggestion is much appreciated
