 Hi @konyoldeath,

 It sounds like some code is passing the incorrect value to the function.
 Would you be able to do some more debugging to determine what's calling
 `wp_list_pluck()`?

 The simplest way would be inspecting the return value of
 [https://developer.wordpress.org/reference/functions/wp_debug_backtrace_summary/
 wp_debug_backtrace_summary()] on the line preceding it:

 {{{
                         foreach ( $this->output as $key => $value ) {
                                 if ( is_object( $value ) ) {
                                         $newlist[ $key ] = $value->$field;
                                 } else {
                                         // Debugging:
                                         if ( ! is_array( $value ) ) {
                                                 error_log(
 wp_debug_backtrace_summary() );
                                                 // or, show it:
                                                 // var_dump(
 wp_debug_backtrace_summary() );
                                         }
                                         $newlist[ $key ] = $value[ $field
 ];
                                 }
                         }
 }}}
