Wordpress how to update ACF field in a custom post type after the post has been saved

I'm trying to set the value of a field in a custom post type right after that post has been created. Here is my code:

add_action('acf/save_post', 'set_coach_email');
function set_coach_email( $post_id ){
    $posttype = get_post_type($post_id);
    if ('team' !== $posttype){
        return;
    }
    $email = 'test@test.com';
    update_field('coach_email', $email, $post_id);
}

I used ACF fields to create this custom post type, but I can't seem to get it to work.

I'd check the opposite conditional check. Also i'd first check if the field is empty or not, then i'd only run the update if the field is empty.

add_action('acf/save_post', 'set_coach_email');

function set_coach_email($post_id)
{
  $posttype = get_post_type($post_id);

  $email_field = get_field('coach_email', $post_id);

  if ('team' == $posttype && empty($email_field)) {

    $email = 'coachtest@test.com';

    update_field('coach_email', $email, $post_id);

  }
}

Just tested on my own custom post type and it worked fine. Let me know if you could get it to work too!

I find sometimes using acf/save_post, upping the priority makes sure everything else has run before running the action function.

This might come into play when passing an $post_id in the get_field() function, I tend not to pass the $post_id when using acf/save_post to make sure the current latest field data is used. But this theory might not be the case. See comments in code below...

<?php

// save post action with priority 20 (default 10)
add_action('acf/save_post', 'set_coach_email', 20);

/**
 * @param $post_id int|string
 */
function set_coach_email($post_id) {

    // get our current post object
    $post = get_post($post_id);

    // if post is object
    if(is_object($post)) {

        // check we are on the team custom type and post status is either publish or draft
        if($post->post_type === 'team' && ($post->post_status === 'publish' || $post->post_status === 'draft')) {

            // get coach email field
            $coach_email = get_field('coach_email');
            
            // if coach email field returns false
            if(!$coach_email) {

                // coach email default
                $email = 'coachtest@test.com';

                // update coach email field
                update_field('coach_email', $email, $post->ID);

            }

        }

    }

    // finally return
    return;

}
