resolves #823

Also extend the change to all the other relational types eg.

data-hub/src/GraphQL/DataObjectInputProcessor/AdvancedManyToManyRelation.php

Lines 47 to 60 in 630d729

	if ($element) {
	$metaData = $newValueItemValue['metadata'] ?? null;
	if ($metaData) {
	foreach ($metaData as $metaDataKey => $metaDataValue) {
	$columns[] = $metaDataValue['name'];
	$data[$metaDataValue['name']] = $metaDataValue['value'];
	}
	}
	$item = new ElementMetadata($fieldName, $columns ?? [], $element);
	if (isset($data) === true) {
	$item->setData($data);
	}
	$result[] = $item;
	}

data-hub/src/GraphQL/DataObjectInputProcessor/ManyToManyObjectRelation.php

Lines 51 to 53 in 3a454f2

	if ($element) {
	$result[] = $element;
	}

or maybe just move the exception to getElementByTypeAndIdOrPath() but may need to change these

data-hub/src/GraphQL/Resolver/QueryType.php

Lines 214 to 217 in e28c7c4

	$assetElement = $this->getElementByTypeAndIdOrPath($args, 'asset');
	if (!$assetElement) {
	return null;
	}

to try-catch
