Magento 2.4.2: redirection from Observer not working

Question

I am getting 'ERR_TOO_MANY_REDIRECTS'. I tried solution from this link: Magento2: redirection from Observer

 public function execute(Observer $observer)
{
    $this->actionFlag->set('', \Magento\Framework\App\Action\Action::FLAG_NO_DISPATCH, true);
    $controller = $observer->getControllerAction();
    $this->redirect->redirect($controller->getResponse(), 'sales/order/history');
}

Edit:

This issue was coming because I have used contoller predispatch events so every controller is redirecting to 'sales/order/history', which include sales/order/history controller, which results in too many Redirects

I'll tell you two ways to redirect from the observer.

1)

$controller = $observer->getControllerAction();
    $this->redirect->redirect($controller->getResponse(), 'customer/account/login');

$controller = $observer->getControllerAction();
$url = $this->getUrl('customer/account/login'); //Magento\Framework\UrlInterface $url
$controller->getResponse()->setRedirect($url);

Example

<?php
namespace Magento\Captcha\Observer;

use Magento\Framework\Event\ObserverInterface;

class CheckForgotpasswordObserver implements ObserverInterface
{
    protected $redirect;
    public function __construct(
        \Magento\Framework\App\Response\RedirectInterface $redirect
    ) {
        $this->redirect = $redirect;
    }

    /**
     * Redirect to login page
     *
     * @param \Magento\Framework\Event\Observer $observer
     * @return $this
     */
    public function execute(\Magento\Framework\Event\Observer $observer)
    {
        /** @var \Magento\Framework\App\Action\Action $controller */
        $controller = $observer->getControllerAction();
        $this->redirect->redirect($controller->getResponse(), 'customer/account/login');

        return $this;
    }
}

Checked this one,

protected $actionFlag; 
protected $redirect; 

public function __construct(
    \Magento\Framework\App\ActionFlag $actionFlag,
    \Magento\Framework\App\Response\RedirectInterface $redirect

) {
    $this->actionFlag = $actionFlag;
    $this->redirect = $redirect;
}

public function execute(\Magento\Framework\Event\Observer $observer)
{
    $this->actionFlag->set('', \Magento\Framework\App\Action\Action::FLAG_NO_DISPATCH, true);
    $this->redirect->redirect($controller->getResponse(), '*/*/edit');
}

This will work for you, Happy Coding
