If you’re into Magento migration then you might face with many errors & solution.

Dropping other errors aside, today, we’re going to talk about a Fatal error that can be faced while product/data migration.

The error is known as Fatal error.

It’s as show below:

“Uncaught Error: Unsupported operand types in /var/www/html/magento1.9/app/code/core/Mage/ImportExport/Model/Export/Entity/Product.php:948”

It can occur when you are trying to export products from admin.

But, where there is an error, there is a solution.

The solution for above problem is replacement of code.

Replace code $dataRow += $stockItemRows[$productId]; on line no. 948 with below code in  app/code/core/Mage/ImportExport/Model/Export/Entity/Product.php file.

-    $dataRow += $stockItemRows[$productId];
+    if (isset($stockItemRows[$productId])) {
+        $dataRow = array_merge($dataRow, $stockItemRows[$productId]);
+    }

With this simple replacement, your will get rid of that fatal error.
