The entity () did not specify a storage.

On node view, if "Entity Reference" field in not empty, I get error:
"The entity () did not specify a storage." at .../core/lib/Drupal/Core/Entity/EntityManager.php line 107

In:
core/modules/entity_reference/lib/Drupal/entity_reference/Plugin/field/formatter/EntityReferenceFormatterBase.php

I needed to change this:
$target_type = $this->field['settings']['target_type'];
to:
$target_type = $this->fieldDefinition['field']['settings']['target_type'];
