How to test react-ideal-image?

[scarletks1214]

• create-react-app,
• npm install --save react-ideal-image react-waypoint prop-types
• added below snippet to App.js
  <IdealImage

  width={800}
  height={800}
  placeholder={{color: 'grey'}}
  srcSet={[{
  width:800,
  size: 800,
  format: 'jpeg',

  />

Now I got below errors.
How can I test the basic usage of this component?

Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

Now I fixed the above issue. But not sure it is the best.
I changed the react-waypoint version to 8.0.3 (Latest version is 9.0.1)

I'd like to know the best solution to this issue.

@scarletks1214 Pretty sure that's the best fix at the moment, I did the same.
