Closing for now, on unit test, this is due to phpunit, on rector side, it show

 [ERROR] Could not process                                                                                              
         "/Users/samsonasik/www/CodeIgniter4/tests/system/Validation/StrictRules/CreditCardRulesTest.php" file, due to: 
         "System error: "Undefined array key 0"                                                                         
         Run Rector with "--debug" option and post the report here: https://github.com/rectorphp/rector/issues/new". On line: 662
