As the title suggests, I’m trying to populate an ACF File field from a Gravity Forms upload field.

Can this be done? Where would one start?

Currently, I have tried this – https://rob.kinsella.dev/gravity-forms-assign-a-file-upload-to-an-advanced-custom-fields-file-field-wordpress-code-snippet/

/**
 * Gravity Forms - handle file field upload and assign to ACF file field
 */

add_action( 'gform_advancedpostcreation_post_after_creation_2', function( $post_id, $feed, $entry, $form ) {
    $file_field_entry_key = 5;

    if ( $image_url = rgar( $entry, $file_field_entry_key ) ) {
        $image_path = $_SERVER['DOCUMENT_ROOT'] . wp_make_link_relative( $image_url );

        require_once( ABSPATH . 'wp-admin/includes/image.php' );
        require_once( ABSPATH . 'wp-admin/includes/file.php' );
        require_once( ABSPATH . 'wp-admin/includes/media.php' );

        $filetype = wp_check_filetype( basename( $image_path ), null );

        $file_array = [
            'name'     => basename( $image_path ),
            'type'     => $filetype,
            'tmp_name' => $image_path,
            'error'    => 0,
            'size'     => filesize( $image_path ),
        ];

        $attachment_id = media_handle_sideload( $file_array, $post_id );

        update_field( 'YOUR_FIELD_NAME', $attachment_id, $post_id );
    }
}, 10, 4 );

The issue with the code that you posted is that is says

update_field( 'YOUR_FIELD_NAME', $attachment_id, $post_id );

If you use the field name as this code suggests, and the field does not already have a value (exists in the database) then the ACF field will not be updated properly. When updating fields that do not already have values you must use the field key instead of the field name.

This is covered in the update_field() documentation https://www.advancedcustomfields.com/resources/acf-update_field/
