Starting at Bricks 1.9.7, you must explicitly allow any function names you want to call via Bricks’ dynamic data echo tag using the new bricks/code/echo_function_names filter. You can add this to your Bricks child theme or the code snippet plugin of your choice.

add_filter( 'bricks/code/echo_function_names', function() {
  return [
    'my_custom_function',
    'another_custom_function',
  ];
} );
add_filter( 'bricks/code/echo_function_names', function($function_name) {
  return [
    '@^brx_', // Allow all functions that start with "brx_"
  ];
} );
