I did a workaround for this, as described here: https://www.drupal.org/project/default_content/issues/3329816#comment-16... ✨ Layout Paragraphs Support Active

I found a workaround for this, and I hope it somehow gives an insight for possible solutions.

I have a node with a paragraph reference field (LVL1) that then has a field reference that aims towards other paragraphs (LVL2). The problem was, as stated before by @nicholass , the LVL 2 paragraphs are mot being exported.

The structure is somehow like this:

Node
------> Paragraph LVL 1
---------------> Paragraph LVL 2 #1
---------------> Paragraph LVL 2 #2

The workaround:

First, I export a node like this:

drush dcer node NODE_ID --folder=../recipes/RECIPE_NAME

Then, I run the following in the command line to identify all the paragraphs IDs that are referenced in LVL2:

drush php-eval '
$node = \Drupal\node\Entity\Node::load(NODE_ID);
$nested_ids = [];

// Loop through first-level paragraphs.
foreach ($node->get("field_PARAGRAPHS_LVL1")->referencedEntities() as $paragraph) {
    if ($paragraph->hasField("field_PARAGRAPHS_LVL2")) {
        foreach ($paragraph->get("field_PARAGRAPHS_LVL2")->referencedEntities() as $nested) {
            $nested_ids[] = $nested->id();
        }
    }
}

// Remove duplicates
$nested_ids = array_unique($nested_ids);
sort($nested_ids);

// Export commands
foreach ($nested_ids as $id) {
    echo "drush dcer paragraph $id --folder=../recipes/RECIPE_NAME\n";
}
'

This will generate a list of commands like this (with the respective LVL2 paragraph IDs):

drush dcer paragraph 24693 --folder=../recipes/RECIPE_NAME 
drush dcer paragraph 24694 --folder=../recipes/RECIPE_NAME 
drush dcer paragraph 24695 --folder=../recipes/RECIPE_NAME 
drush dcer paragraph 24696 --folder=../recipes/RECIPE_NAME

Then, by running those commands, all paragraphs get generated under the RECIPE_NAME/paragraph/ folder.

Then, importing will work (paragraphs will be created and properly referenced from the LVL1 paragraph and the Node). The problem is actually occurs during the export.

Hope it helps!
