I was making a web app on Difinity’s Internet Computer using Motoko language but when I try to call a query function from my frontend I got the Uncaught runtime error saying – ‘Timestamp not found in query response. This suggests a malformed or malicious response.’
My query functions are not working

I made this query function –

    stable var currentValue: Float= 100;
    public query func checkBalance (): async Float {
          return currentValue;
    };

I call it from my index.js file like this –

    import { dbank} from "../../declarations/dbank";

    window.addEventListener('load', async () => {

        let currentValue = await dbank.checkBalance();
        document.getElementById("value").innerText = currentValue;
    });

**And I got this error **-

Timestamp Error
