I am running into a exception where creating child docs fails unless the field already exists in the schema (stacktrace is at the bottom of this post). My solr is v8.5.1 running in standard/non-cloud mode.
$> curl -X POST -H 'Content-Type: application/json' 'http://localhost:8983/solr/mycore/update' --data-binary '[{ "id": "3dae27db6ee43e878b9d0e8e", "phone": "+1 (123) 456-7890", "myChildDocuments": [{
