Default values for sub field: Post Object

I have a repeater field with 2 sub fields:
GAS NAME (Post object field from Custom Post Type: Gas)
GAS VALUE (number field)

Below code can set default values for sub fields within a repeater field. The GAS VALUE (set to 0 in below example) works but this code doesn’t work for the GAS NAME, probably because its a Post Object field.

Anyone knows how to set default values for a Post Object sub field?

Thanks!

add_filter('acf/load_value/key=field_5e23ef1222ea5',  'yl_pre_load_default_gasses', 10, 3);
function yl_pre_load_default_gasses($value, $post_id, $field) {

  if ($value === false) {

    $value = array();

    $value[] = array(
      'field_5e23ef3a22ea6' => 'Title 1', // Post object field (CUSTOM POST TYPE: GAS)
      'field_5e23f00922ea7' => '0'
    );
    $value[] = array(
      'field_5e23ef3a22ea6' => 'Title 2', // Post object field (CUSTOM POST TYPE: GAS)
      'field_5e23f00922ea7' => '0'
    );
  }

  return $value;
}

I’m not sure if this is helpful to you, but I just got a similar filter to work when the Post Object sub-field of the Repeater has the Return Format set to “Post ID”. With this setting, I just passed in the appropriate post_id as the value in the filter. So with your code above it’d be something like:

if ($value === false) {

    $value = array();
    $post_id_1 = 28;
    $post_id_2 = 24;
  
    $value[] = array(
      'field_5e23ef3a22ea6' => $post_id_1, // post_id of the 1st Gas post that you want to choose
      'field_5e23f00922ea7' => '0'
    );
    $value[] = array(
      'field_5e23ef3a22ea6' => $post_id_2, // post_id of the 2nd Gas post that you want to choose
      'field_5e23f00922ea7' => '0'
    );
  }

  return $value;
