reactjs - Cannot connect my AWS api gateway with my local host

Question

When I try to submit my form using from local host reactjs it showing console error:

"Missing required key 'TableName' in params", code: "MissingRequiredParameter", time: "2021-01-06T06:40:42.102Z"}.

Using AWS amplify for frontend and backend.

The post call is:

app.post('/contact', function(req, res) {
    console.log(req);
    var params = {
        Tablename: process.env.STORAGE_FORMTABLE_NAME,
        Item: {
            id: id(),
            name: req.body.name,
            email: req.body.email,
            phonenumber: req.body.phonenumber,
            address: req.body.address,
            message: req.body.message
        }
    }
    docClient.put(params, function(err, data) {
        if (err) res.json({
            err
        })
        else res.json({
            success: 'Contact created successfully!'
        })
    })
});
