Seems that (at least with MySQL 5.7.23) if you do not set an _id field in the array of items to "add", it fails with error...
[HY000] Document is missing a required field
Adding "_id" => xxxx does resolve the issue.

Collection::add — Add collection document
Triggers the insertion of the given document(s) into the collection, and multiple variants of this method are supported. Options include:
Add a single document as a JSON string.
Add a single document as an array as:
[ 'field' => 'value', 'field2' => 'value2' ... ]
A mix of both, and multiple documents can be added in the same operation.
documentOne or multiple documents, and this can be either JSON or an array of fields with their associated values. This cannot be an empty array.
The MySQL server automatically generates unique _id values for
each document (recommended), although this can be manually added as well. This value must be
unique as otherwise the add operation will fail.
A CollectionAdd object. Use execute() to return a Result that can be used to query the number of affected items, the number warnings generated by the operation, or to fetch a list of generated IDs for the inserted documents.
Приклад #1 mysql_xdevapi\Collection::add() example
<?php
$session = mysql_xdevapi\getSession("mysqlx://user:password@localhost");
$session->sql("DROP DATABASE IF EXISTS addressbook")->execute();
$session->sql("CREATE DATABASE addressbook")->execute();
$schema = $session->getSchema("addressbook");
$create = $schema->createCollection("people");
$collection = $schema->getCollection("people");
// Add two documents
$collection->add('{"name": "Fred", "age": 21, "job": "Construction"}')->execute();
$collection->add('{"name": "Wilma", "age": 23, "job": "Teacher"}')->execute();
// Add two documents using a single JSON object
$result = $collection->add(
'{"name": "Bernie",
"jobs": [{"title":"Cat Herder","Salary":42000}, {"title":"Father","Salary":0}],
"hobbies": ["Sports","Making cupcakes"]}',
'{"name": "Jane",
"jobs": [{"title":"Scientist","Salary":18000}, {"title":"Mother","Salary":0}],
"hobbies": ["Walking","Making pies"]}')->execute();
// Fetch a list of generated ID's from the last add()
$ids = $result->getGeneratedIds();
print_r($ids);

Зауваження:
A unique _id is generated by MySQL Server 8.0 or higher, as demonstrated in the example. The _id field must be manually defined if using MySQL Server 5.7.

[HY000] Document is missing a required field
Adding "_id" => xxxx does resolve the issue.It returns a mysql_xdevapi\CollectionAdd instead of a mysql_xdevapi\Result
