The value your including in the call to update_field in incorrect then. What you have there is the field settings for the entire field. Look at the documentation for update_field here https://www.advancedcustomfields.com/resources/update_field/

What you want will look something like this

update_field('field_0123456789', array(1,2,5), $post_id);
