Magic login link not working - SHIELD CI4

I am using shield for Authorization, I have created API to send magic login link, email receives with magic link. when I click on link, it's makes the user login.
Earlier this whole process was working fine, but now suddenly stopped. 
I tried to test the default links as well, that too not working. Showing "Unable to verify the link." error
https://prnt.sc/Ws3I6O-RFjMA

Below is my code

PHP Code:

public function forgotPassword() {
        $currentLang = $this->request->getVar("lang") ?? DEFAULT_LANGUAGE;
        $this->request->setLocale($currentLang);

        $rules = [
            "email"      => "required|valid_email"
        ];

        if(!$this->validate($rules)){
            $response = [
                "status"    => false,
                "message"  => $this->validator->getErrors(),
                "data"      => []
            ];
        } else {

            $userEmail = $this->request->getVar('email');
            $users = auth()->getProvider();
            
            $user = $users->findByCredentials(['email' => $userEmail]);

            if($user){
                $firstName = $user->first_name;

                // Generate a unique token
                $token = bin2hex(random_bytes(16));

                // Store the token in the user's session or any temporary storage
                $session = session();
                $session->set('magic_link_token', $token);

                // Generate the magic link URL
                $magicLinkUrl = site_url("api/magic-login/{$token}");

                // sending email  here
                sendEmail($emailData);

                $response = [
                    "status"    => true,
                    //"message"  => 'Magic link sent on your email. Please login with this link and update your password.',
                    "message"  => lang('App.forgot_success'),
                    "data"      => ['magic_link_url' => $magicLinkUrl]
                ];
            } else {
                $response = [
                    "status"    => false,
                    "message"  => lang('App.email_notExist'),
                    "data"      => []
                ];
            }
            
        }

        return $this->respondCreated($response);
    } 


Here is my code to verify link

PHP Code:

public function magicLogin($token)
    {
        $currentLang = $this->request->getVar("lang") ?? DEFAULT_LANGUAGE;
        $this->request->setLocale($currentLang);
        
        // Retrieve the token from the URL parameter
        // Validate the token, you may check it against the session or temporary storage
        $session = session();
        $storedToken = $session->get('magic_link_token');

        if ($token === $storedToken) {
            // Token is valid, log the user in
            $user = auth()->user();

            $token = $user->generateAccessToken(SECRET_KEY);
            $auth_token = $token->raw_token;

            // Return a success message as a JSON response
            $response = [
                "status"    => true,
                "message"  => lang('App.login_success'),
                "data"      => ['token' => $auth_token]
            ];
        } else {
            // Invalid token
            $response = [
                "status"    => false,
                "message"  => lang('App.invalid_link'),
                "data"      => []
            ];
        } 

        return $this->respondCreated($response);
    }

Thanks for the reply, I understand this link helpful to validate the incoming request, But I can't under how this resolve my issue.
Here is the old screenshot of my code execution, by using the magic link, I was able to authorise the user.

I am not understanding how does code stopped working suddenly.
Thanks

Shield is too complicated to implement when connected to a project for a beginner

@pratibha.cts, I see nothing wrong with your code, I said the above because they say not to use getVar anymore.

Can you check and make sure that your email is working, google has been making email login changes that effect this.

Google does not allow less security if they now use API which is the main reason it was from my side too

Codeigniter First, Codeigniter Then You!!

You can use your internet providers SMTP Mail server if you have internet connection.

I have Comcast and I use their SMTP Mail server for testing my emails.

Are you using the newest version of postman, they had problems with some older versions.

Your Error is stating that the token is NULL.

Check your generateToken() method etc.
