  • Please share the full code Action file? – Amit Bera Jan 29 at 14:34

  • Is this frontend URL? – Amit Bera Jan 29 at 14:56

As this frontend URL

Then you cannot inject admin context class \Magento\Backend\App\Action\Context $context, here. That way you are getting the error.

Change this class to \Magento\Framework\App\Action\Context $context

after that do the Di compile properly.

    wait, how do you know that it's a backend request? Does not seem like it. I would argue that the Interceptor class likely must be deleted / regenerated – David Verholen Jan 29 at 14:54
  • aah,you are right. We are not sure this is frontend or admin URL. – Amit Bera Jan 29 at 14:56
  • its frontend url – Nasouh Jan 29 at 14:58
  • what do you mean by "Di compile" ? – Nasouh Jan 29 at 15:05
  • setup:di: compile – Amit Bera Jan 29 at 15:14

Use \Magento\Framework\App\Action\Context $context

Instead of :

\Magento\Backend\App\Action\Context $context
