// 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();

import React, { Component } from "react";

const AmazonContext = React.createContext();

export class Provider extends Component {
  state = {
    Images: [
      {
        SliderImages: []
      }
    ]
  };

  render() {
    return (
      <AmazonContext.Provider
        value={{
          Images: this.state.Images,
          actions: {}
        }}
      >
        {this.props.children}
      </AmazonContext.Provider>
    );
  }
}

export default Provider;

export const Consumer = AmazonContext.Consumer;

The way you're exporting the Provider and Consumer is causing issue. Export one as default and other one as module.
