Why TYPO3 calls a wrong File Reference table - typo3

Question

I have a Model for a Products table with this code to get the images references:
/**
* Returns the images
*
* #return \TYPO3\CMS\Core\Resource\FileReference $images
*/
public function getImages() {
$fileRepository = GeneralUtility::makeInstance(\TYPO3\CMS\Core\Resource\FileRepository::class);
$this->images = $fileRepository->findByRelation('tx_myext_domain_model_products', 'images', $this->uid);
return $this->images;
}
But it triggers an error:
ERROR => 'Table 'database.tx_core_resource_filereference' doesn't exist'
Don't sure why this table name is used. sys_file_reference is the name of the real table in the database.

If this is in the domain as you suggested, then all you should need is:
.../Classes/Domain/Model/Product.php
...
/**
* images
*
* #var \TYPO3\CMS\Extbase\Domain\Model\FileReference
*/
protected $images = null;
/**
* Returns the images
*
* #return \TYPO3\CMS\Extbase\Domain\Model\FileReference images
*/
public function getImages()
{
return $this->images;
}
/**
* Sets the images
*
* #param \TYPO3\CMS\Extbase\Domain\Model\FileReference $images
* #return void
*/
public function setImages(\TYPO3\CMS\Extbase\Domain\Model\FileReference $images)
{
$this->images = $images;
}
...
Then the TCA for products would require config for images... for example:
.../Configuration/TCA/tx_yourext_domain_model_product.php
...
'images' => [
'label' => 'FAL Image',
'config' => \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::getFileFieldTCAConfig(
'images',
[
'appearance' => [
'createNewRelationLinkTitle' => 'LLL:EXT:cms/locallang_ttc.xlf:images.addFileReference'
],
// custom configuration for displaying fields in the overlay/reference table
// to use the image overlay palette instead of the basic overlay palette
'overrideChildTca' => [
'types' => [
'0' => [
'showitem' => '
--palette--;LLL:EXT:lang/locallang_tca.xlf:sys_file_reference.imageoverlayPalette;imageoverlayPalette,
--palette--;;filePalette'
],
\TYPO3\CMS\Core\Resource\File::FILETYPE_TEXT => [
'showitem' => '
--palette--;LLL:EXT:lang/locallang_tca.xlf:sys_file_reference.imageoverlayPalette;imageoverlayPalette,
--palette--;;filePalette'
],
],
],
],
$GLOBALS['TYPO3_CONF_VARS']['GFX']['imagefile_ext']
),
],
...

Seems like you use a wrong FileReference. Check if you import the correct one in your Model:
Wrong:
use TYPO3\CMS\Core\Resource\FileReference;
Correct:
use TYPO3\CMS\Extbase\Domain\Model\FileReference;
