Summary0002166: Gettype type doesn't match during step debug

While step debugging using VSCode, I found some unexpected behavior, and have no idea if Xdebug has anything do wtih this issue,

I'm running a cli script that loads WordPress before running.
At the point of execution in question, I expect a particular value( 1 ) to be stored in array location( $the_['accepted_args'] ).

The debugger reports the value as 1 (with no quotes) as expected, but it evaluates to 0/NULL at the same time.

  • $the_['accepted_args'] is reported to be 1
  • gettype($the_['accepted_args']) produces NULL
  • (int) $the_['accepted_args'] produces 0.

For some context, all the checks are performed while execution is paused on in WordPress apply_filters function.
It happens on in class-wp-hook.php#L310

Thanks for any suggestions!

Steps To Reproduce

Couldn't reproduce on another machine..

THe issue happened after loading WordPress and then running the blow code block.

function mc_test($one){
return $one;
add_filter('mc_test', 'mc_test', 10, 1);
$maybe_single_param = apply_filters('mc_test', 'single-param');
