I am trying to understand this exception: Unknown entity type: NamespaceModuleModelName requested

I have a module and I am loading it like this in my controller:

$model = $this->_objectManager->create(NamespaceModuleModelName::class);
$model->load($id);

and in my resource model: class NamespaceModuleModelResourceModelName, I have this:

/**
 * Load an object
 *
 * @param AbstractModel $object
 * @param mixed $value
 * @param string $field field to load by (defaults to model id)
 * @return $this
 * @SuppressWarnings(PHPMD.UnusedFormalParameter)
 */
public function load(AbstractModel $object, $value, $field = null)

 $this->getEntityManager()->load($object, $value);
 return $this;

Then in my di.xml, I have got this:

<type name="MagentoFrameworkModelEntityRepositoryFactory">
 <arguments>
 <argument name="entities" xsi:type="array">
 <item name="NamespaceModuleApiDataNameInterface" xsi:type="string">NamespaceModuleModelResourceModelName</item>
 </argument>
 </arguments>
</type>
<type name="MagentoFrameworkEntityManagerMetadataPool">
 <arguments>
 <argument name="metadata" xsi:type="array">
 <item name="NamespaceModuleApiDataNameInterface" xsi:type="array">
 <item name="entityTableName" xsi:type="string">my_table</item>
 <item name="identifierField" xsi:type="string">my_id</item>
 </item>
 </argument>
 </arguments>
</type>


<type name="MagentoFrameworkEntityManagerOperationAttributePool">
 <arguments>
 <argument name="extensionActions" xsi:type="array">
 <item name="myName" xsi:type="array">
 <item name="NamespaceModuleApiDataNameInterface" xsi:type="array">
 <item name="read" xsi:type="string">NamespaceModuleModelResourceModelReadHandler</item>
 <item name="create" xsi:type="string">NamespaceModuleModelResourceModelSaveHandler</item>
 <item name="update" xsi:type="string">NamespaceModuleModelResourceModelSaveHandler</item>
 </item>
 </item>
 </argument>
 </arguments>
</type>

Why is that throwing the exception?

How do I understand this MetadataPool?

UPDATE 1

I have checked further and found that MagentoFrameworkEntityManagerMetadataPool::getMetadata($entityType) is receiving NamespaceModuleModelName as argument. It supposed to receive NamespaceModuleApiDataNameInterface.

Doing var_dump($this->metadata) does shows there is NamespaceModuleApiDataNameInterface in the $this->metadata array.

What am I missing?

 <!-- Register the Abstract Repositories -->
<type name="MagentoFrameworkModelEntityRepositoryFactory">
 <arguments>
 <argument name="entities" xsi:type="array">
 <item name="NamespaceModuleApiNameRepositoryInterface" xsi:type="string">NamespaceModuleApiNameRepositoryInterface</item>
 </argument>
 </arguments>
</type>

Right, so I have forgotten to implement NameInterface to my model Name.

Once added the interface implementation, right $entityType was passed and was loading successfully.

<?php 
namespace NamespaceModuleModel;

class Name extends MagentoFrameworkModelAbstractExtensibleModel implements NamespaceModuleApiDataNameInterface

And, obviously <preference for="NamespaceModuleApiDataNameInterface" type="NamespaceModuleModelName" /> in my di.xml

Hope this helps someone.
