Object with identity "1234" not found.

Error like that is thrown when you have an Extbase plugin on a page with a "single view" action, and the object with id 1234 can not be retrieved. E.g. because it is hidden or deleted.

Example for TYPO3 8.7:

/**
  * @param \TYPO3\CMS\Extbase\Mvc\RequestInterface $request
  * @param \TYPO3\CMS\Extbase\Mvc\ResponseInterface $response
  * @throws \Exception|\TYPO3\CMS\Extbase\Property\Exception
  */
 public function processRequest(\TYPO3\CMS\Extbase\Mvc\RequestInterface $request, \TYPO3\CMS\Extbase\Mvc\ResponseInterface $response)
 {
     try {
         parent::processRequest($request, $response);
     }
     catch(\TYPO3\CMS\Extbase\Property\Exception\TargetNotFoundException $e) {
         if ($e instanceof \TYPO3\CMS\Extbase\Property\Exception\TargetNotFoundException) {
             $GLOBALS['TSFE']->pageNotFoundAndExit('The given id could not be mapped to an object.');
         } else {
             throw $e;
         }
     }
 }

In TYPO3 9.5, you can switch out the (now deprecated) pageNotfoundAndExit()-code with this:

return GeneralUtility::makeInstance(ErrorController::class)->pageNotFoundAction(
  $this->request,
  'The requested page does not exist',
  ['code' => PageAccessFailureReasons::PAGE_NOT_FOUND]
);
