Super hero wallet Connection

Hi, I’m trying to connect superhero wallet to my Daepp, but I’m getting this error below

Uncaught (in promise) MissingCallbackError: Can't find callback for this messageId 1
    at RpcClient._processResponse2

Unhandled Runtime Error
MissingCallbackError: Can't find callback for this messageId 2

Here is the connection code I wrote

import { AeSdkAepp, BrowserWindowMessageConnection, SUBSCRIPTION_TYPES, Node, walletDetector } from '@aeternity/aepp-sdk'

export const scanForWallet = async (aeSdk : AeSdkAepp) => {
     return new Promise((resolve, reject) => {
        if(!aeSdk) reject("Failed!, SDK is not initialized.");
        const scannerConnection = new BrowserWindowMessageConnection()
        const handleNewWallet = async ({ wallets, newWallet} : any) => {
            const wallet = newWallet || Object.values(wallets)[0]
            await aeSdk.connectToWallet(await wallet.getConnection());

            await aeSdk.subscribeAddress(
                // @ts-ignore

        const stopScan = walletDetector(

export const iniSDK = async () => {
    try {
    const aeSdk = new AeSdkAepp({
        name: 'Skaker',
            nodes: [ 
                    name: 'ae_uat',
                    instance: new Node(""),
            compilerUrl: "",
            onAddressChange: (p) => console.log("onAddressChange", p),
            onDisconnect: (p) => console.log("onDisconnect", p),
            onNetworkChange: (p) => console.log("onNetworkChange", p)

        await scanForWallet(aeSdk)

        return aeSdk;

I don’t know what I did wrong

Thanks for reaching out to us @paschal533, great to see you developing an æpplication with a Supero wallet connection. Maybe @davidyuk or @marco.chain could help out here?

did you remember what was the exact issue? We can publish the resolution to help with similar problems in future


The problem was from my local environment. I deployed the app to netlify, and I stopped seeing the error. And everything works perfect after the deployment.
