How to diagnose the «Imported resource (image) could not be downloaded from external resource due to timeout or access permissions» failure on a product import?

How is the message generated?

magento/magento2/blob/d447fa6e1/app/code/Magento/CatalogImportExport/Model/Import/Product.php#L260-L260


ValidatorInterface::ERROR_MEDIA_URL_NOT_ACCESSIBLE => 'Imported resource (image) could not be downloaded from external resource due to timeout or access permissions',

magento/magento2/blob/d447fa6e1/app/code/Magento/CatalogImportExport/Model/Import/Product.php#L1547-L1562


foreach ($rowImages as $column => $columnImages) {
    foreach ($columnImages as $position => $columnImage) {
        if (!isset($uploadedImages[$columnImage])) {
            $uploadedFile = $this->uploadMediaFiles(trim($columnImage), true);
            if ($uploadedFile) {
                $uploadedImages[$columnImage] = $uploadedFile;
            } else {
                $this->addRowError(
                    ValidatorInterface::ERROR_MEDIA_URL_NOT_ACCESSIBLE,
                    $rowNum,
                    null,
                    null,
                    ProcessingError::ERROR_LEVEL_NOT_CRITICAL
                );
            }
        } else {

So the \Magento\CatalogImportExport\Model\Import\Product::uploadMediaFiles() method misses an actual exception report.

How to fix it

Locate the line:

Add a new line just above:

$this->_logger->critical($e);

Using the critical() we log the exceptions into the exception.log file.

Magento team has implemented my fix after 2 years at 2018-01-10 in Magento 2.3. Great reaction!
