Hi Team,

getting the following error while opening any product

Fatal error: Uncaught TypeError: Return value of ProductAssemblerCore::addMissingProductFields() must be of the type array, null returned in /home/simba/simbaweb.com/classes/ProductAssembler.php:111 Stack trace: #0 /home/simba/simbaweb.com/classes/ProductAssembler.php(125): ProductAssemblerCore->addMissingProductFields(Array) #1 /home/simba/simbaweb.com/modules/ps_viewedproduct/ps_viewedproduct.php(253): ProductAssemblerCore->assembleProduct(Array) #2 /home/simba/simbaweb.com/modules/ps_viewedproduct/ps_viewedproduct.php(195): Ps_Viewedproduct->getViewedProducts(36) #3 /home/simba/simbaweb.com/modules/ps_viewedproduct/ps_viewedproduct.php(181): Ps_Viewedproduct->getWidgetVariables('displayFooterPr...', Array) #4 /home/simba/simbaweb.com/classes/Hook.php(994): Ps_Viewedproduct->renderWidget('displayFooterPr...', Array) #5 /home/simba/simbaweb.com/classes/Hook.php(938): HookCore::coreRenderWidget(Object(Ps_Viewedproduct), 'displayFooterPr...', Array) #6 /home/zp in /home/simba/simbaweb.com/classes/ProductAssembler.php on line 111

What's your PHP? Is that theme is updated to work on PS 8?

Temporary disable this module "ps_viewedproduct", clear cache and check.

I have the same issue. PHP version 7.4 and running in "FPM application" mode.

Prestashop v. 1.7.8.8

Hi ,

When this error occurs in my shop, I come up with this solution.

In ProductAssembler.php:111, make this changes.

 

        if ($rows === false) {
            return $rawProduct;
        }
        //  ****
  $mergedData = array_merge($rows[0], $rawProduct);

    if (!is_array($mergedData)) {
        throw new Exception("La méthode addMissingProductFields doit retourner un tableau.");
    }

    return $mergedData;
    // ********
    }
