Variable Replacement Callback Function Error

When doing the following…

/**
* Action: ‘rank_math/vars/register_extra_replacements’ – Allows adding extra variables.
*/

add_action( ‘rank_math/vars/register_extra_replacements’, function(){
rank_math_register_var_replacement(
‘ait_item_address’,
[
‘name’ => esc_html__( ‘Ait Item Address.’, ‘rank-math’ ),
‘description’ => esc_html__( ‘Custom variable description.’, ‘rank-math’ ),
‘variable’ => ‘ait_item_address’,
‘example’ => get_ait_item_address(),
],
‘get_ait_item_address()’
);
});

function get_ait_item_address(){
return ‘address’;
}

The following error appears on the front end CPT where I used the variable.
