Getting partial NEW.<value> using AFTER INSERT trigger - sql

Question

I'm trying to learn PostgreSQL. Now I came across a triggers, and I've wanted to create a trigger to 'copy' inserted data to another table.
I've managed to put together a function and an trigger. But every time I attempt to insert the data, I get partial data to the NEW.nameOfTheRow.
Image as Example on data that I should receive in the user_entity table:
And here is the data that is getting inserted by the function in the Employee table:
And here's the table user_entity:
Here is the table "Employee":
Here's the code for the trigger:
CREATE OR REPLACE TRIGGER sync_two_tables_on_insert
AFTER INSERT ON user_entity
FOR EACH ROW
EXECUTE PROCEDURE sync_employee_with_keycloak_entity();
And here's the code for the function:
CREATE OR REPLACE FUNCTION sync_employee_with_keycloak_entity() RETURNS trigger AS $$
BEGIN
-- This script is not optimized by all means, it will attempt to add data with brute force,
-- Ideally, we would like to do some checking's before attempting to transfer data,
-- "Type" row is not 'valid' here, as the data is not correct, the only reason I've put it there is because it is set to Not Null
-- TODO: Optimize whole script, make validation checks, add error handlers, filter to not pass duplicates.
INSERT INTO "Employees" ("Id", "Email", "FirstName", "LastName", "Alias", "Type")
VALUES(new.id::uuid, new.email, new.first_name, new.last_name, new.username, new.not_before)
ON CONFLICT DO NOTHING;
RETURN NULL;
END
$$
LANGUAGE plpgsql;
I don't understand why I don't get new data on NEW.email, NEW.first_name, NEW.last_name
But I do get correct data on NEW.id, NEW.username and NEW.not_before.
