Forbidden error

[mnlbox]

Hi @Pritoj,
I try to use this awesome plugin but it's return Forbiden error. It's my code:

/// IMPORTANT to import like this.
import Strapi from 'strapi-sdk-javascript/build/main';
import strapiDataProvider from 'ra-dp-strapi';
import React from 'react';
import { render } from 'react-dom';
import { Admin, Resource } from 'react-admin';
import { TestList } from './tests/list';

const apiUrl = 'http://localhost:1337';
const strapi = new Strapi(apiUrl);


class App extends React.Component {
  render() {
    return (
        <Admin dataProvider={strapiDataProvider(strapi)}>
            <Resource name="tests" list={TestList}/>
        </Admin>
    );
  }
}

export default App;

// in list.js
import React from 'react';
import { List, Datagrid, Edit, Create, SimpleForm, DateField, TextField, EditButton, DisabledInput, TextInput, LongTextInput, DateInput } from 'react-admin';
import BookIcon from '@material-ui/icons/Book';
export const PostIcon = BookIcon;

export const TestList = (props) => (
    <List {...props}>
        <Datagrid>
            <TextField source="id" />
            <TextField source="title" />
            <DateField source="description" />
        </Datagrid>
    </List>
);

Can you guide me to fix this?
