Please Run below command and check once

php bin/magento setup:di:compile

this will generates DI configuration and all missing classes that can be auto-generated

  • Don't know what was the issue behind it, but since I was using Bitnami VM so stopped the VM and started again and 404 error disappeared now and the code is working as expected.

I think it because your controller did not return correct type. Controller should return type page Magento\Framework\Controller\ResultFactory if you want to use this url as a page.

if it's only a execute controller you can handle logic and return redirect to another page. DI Magento\Framework\Controller\Result\RedirectFactory and then return $this->resultRedirectFactory->create()->setPath('*/*/');

Hope it help

  • Thanks for your answer, but the issue was 404, and apparently it was related to the router before reaching to controller execute method. However, issue is resolved now after I restarted the Bitnami VM.
