Hi. thanks for the git and the tutorial. I Followed the instructions closely. I can register users. However I get a 500 error here: http://test.lan/php-jwt-example/api/login.php

{ "email": "[email protected]", "password": "1234567" }

PHP Fatal error: Uncaught ArgumentCountError: Too few arguments to function Firebase\\JWT\\JWT::encode(), 2 passed in /test/public_html/php-jwt-example/api/login.php on line 65 and at least 3 expected in /test/public_html/php-jwt-example/vendor/firebase/php-jwt/src/JWT.php:183

Stack trace:#0 /test/public_html/php-jwt-example/api/login.php(65): Firebase\\JWT\\JWT::encode() #1 {main} thrown in /test/public_html/php-jwt-example/vendor/firebase/php-jwt/src/JWT.php on line 183

here is line 65:
$jwt = JWT::encode($token, $secret_key);

It works with this: $jwt = JWT::encode($payload, $key, 'HS256');
Taken from here: https://github.com/firebase/php-jwt
I suspect the jwt argument requirements have changed since this was written.
