Invalid totp

[hemil.quarec]

Here is my code

// Initialize SmartAPI
let smart_api;
try {
    smart_api = new SmartAPI({
        api_key: process.env.SMART_API_KEY,    // Your API Key
        clientId: process.env.CLIENT_ID,       // Your Client ID
        clientSecret: process.env.CLIENT_SECRET // Your Client Secret
    });
    console.log('SmartAPI initialized successfully');
} catch (error) {
    console.error('Error initializing SmartAPI:', error);
    process.exit(1);
}

// Store session data
let session = null;

// Session check middleware
const checkSession = (req, res, next) => {
    if (!session || !session.feedToken) {
        return res.status(401).json({ success: false, message: 'Not logged in or session expired' });
    }
    next();
};

//login code test
app.post('/api/login', async (req, res) => {
    try {
        console.log('Login attempt started...');
        const { client_code, password, totp } = req.body;
        
        if (!client_code || !password || !totp) {
            throw new Error('Missing required login parameters');
        }

        console.log('Generating session...');
        const data = await smart_api.generateSession(client_code, password, totp);
        
        console.log('Full API Response:', JSON.stringify(data, null, 2));

        if (!data) {
            throw new Error('Session generation failed, missing tokens.');
        }

        console.log('Session generated successfully:', {
            hasAccessToken: !!data.accessToken,
            hasRefreshToken: !!data.refreshToken,
            hasJwtToken: !!data.jwtToken,
            hasFeedToken: !!data.feedToken
        });

        session = data;
        smart_api.jwtToken = data.jwtToken;
        smart_api.feedToken = data.feedToken;

        res.json({
            success: true,
            message: 'Login successful',
            sessionInfo: {
                hasAccessToken: !!data.accessToken,
                hasJwtToken: !!data.jwtToken,
                hasFeedToken: !!data.feedToken
            }
        });

    } catch (error) {
        console.error('Login error details:', error);
        res.status(500).json({
            success: false,
            message: error.message || 'Login failed',
            errorDetails: error.toString()
        });
    }
});
