Unhandled Rejection (TypeError): Moralis.start is not a function — Moralis version 0.6.08 doesn't fix it

Hi! Someone already shared this error; however, I am getting the same error, updated moralis in package.json to “moralis”: “0.6.08” and this didn’t fix the issue:

is someone able to help me with this issue?

Here is my index.js file

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import { MoralisProvider } from "react-moralis";
// import reportWebVitals from './reportWebVitals';

  // <React.StrictMode>
    <App />
  // </React.StrictMode>,

// If you want to start measuring performance in your app, pass a function
// to log results (for example: reportWebVitals(console.log))
// or send to an analytics endpoint. Learn more: https://bit.ly/CRA-vitals
// reportWebVitals();

Here is my package.json dependencies:

"dependencies": {
    "@emotion/react": "^11.4.1",
    "@emotion/styled": "^11.3.0",

    "styled-components": "^5.3.1",
    "web-vitals": "^1.0.1",
    "web3modal": "^1.9.4"

Also, if this is helpful, my authentication function to login with Metamask (that works in another project 100%) is returning this error message:

You need to call Parse.initialize before using Parse.

I would think it maybe has to do with the server? But I am not sure…

Please try updating the npm package and try running it. The latest versions would look like this -

    "moralis": "^0.0.88",
    "react-moralis": "^0.2.6",

Let us know once updated.

Life saver! Thank you so much @malik!!! You rock.

I do have a random question — I use this “outdated” version of Moralis in another project and it works 100% fine. Is there a reason why it would work in an app I shipped last week, but not for a new project I started this week?

There was an update on Moralis sdk starting with version 0.0.80 that added the syntax with Moralis.start and removed the previous syntax to set server url and application id.
