Call to a member function getValue() on null to fetch store config value in Magento 2.4.6

Question

There is error Call to a member function getValue() on null magento 2.4.6 after upgrading from Magento 2.3.3 to 2.4.6. It was working fine with earlier Magento 2 version. Here is code:

public function isModuleEnable() {
    $storeScope = \Magento\Store\Model\ScopeInterface::SCOPE_STORE;
    return $this->scopeConfig->getValue('ordergrid/general/enable', $storeScope);
}

The system.xml file is fine as it was working earlier. It's throwing error on getValue on null.

Answer 1

have you checked the value of ordergrid/general/enable path in core_config_data ?

Answer 2

You need to add the Magento\Store\Model\ScopeInterface class in your constructor:

Code like below

protected $_scopeConfig;

public function __construct(
     ...
     \Magento\Store\Model\ScopeInterface $scopeInterface,
     ...
)
{
    ...
    $this->_scopeConfig = $scopeInterface;
    ...
}


public function isModuleEnable() {
    $storeScope = \Magento\Store\Model\ScopeInterface::SCOPE_STORE;
    return $this->scopeConfig->getValue('ordergrid/general/enable', $storeScope);
}
