エラー / 例外

Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.
Throws MongoDB\Driver\Exception\CommandException if the server could not commit the transaction (e.g. due to conflicts, network issues). In case the exception's MongoDB\Driver\Exception\CommandException::getResultDocument() has a "errorLabels" element, and this array contains a "TransientTransactionError" or "UnknownTransactionCommitResult" value, it is safe to re-try the whole transaction. In newer versions of the extension, MongoDB\Driver\Exception\RuntimeException::hasErrorLabel() should be used to test for this situation instead.
Throws MongoDB\Driver\Exception\RuntimeException if the transaction could not be commited (e.g. a transaction was not started).
