I am facing below issue in server. It's working fine in my local but in server not working. This error coming while saving the newsletter in My Account page, Sign Up Newsletter in registration page.

Fatal error: Uncaught TypeError: Argument 1 passed to Magento\Eav\Model\Entity\Attribute\Source\Config::__construct() must be of the type array, null given, called in /chroot/home/sitehtml/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php on line 93 and defined in /chroot/home/sitehtml/vendor/magento/module-eav/Model/Entity/Attribute/Source/Config.php:26 Stack trace: #0 /chroot/home/sitehtml/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php(93): Magento\Eav\Model\Entity\Attribute\Source\Config->__construct(NULL) #1 /chroot/home/sitehtml/vendor/magento/framework/ObjectManager/Factory/Compiled.php(88): Magento\Framework\ObjectManager\Factory\AbstractFactory->createObject('Magento\\Eav\\Mod...', Array) #2 /chroot/home/sitehtml/vendor/magento/framework/ObjectManager/ObjectManager.php(57): Magento\Framework\ObjectManager\Factory\Compiled->create('Magento\\Eav\\Mod...', Array) #3 / in /chroot/home/sitehtml/vendor/magento/module-eav/Model/Entity/Attribute/Source/Config.php on line 26

For this error I tried the php bin/setup:di:compile command but no use and I deleted the files in var/generation,var/di, var/cache and I tried the same command but still same issue coming. Please tell me any idea to fix this.

In mailchimp extension go to helper/data.php file


try {
                if($item->usesSource()) {
                    $options = $item->getSource()->getAllOptions();
                } else {
                    $options = [];

Replace with

   try {
                    $options =$item->getSource()->getAllOptions();
                  $options = [];
                catch(\Exception $e) {

                    $options = [];

I think it should work
