Hey @louis-pvs I'm having the same problem.

I belive that problem is PropTypes.oneOfType. If you stop use it, the error not is shown.

I didn't try <PropsTable> using oneOfType in prop types, I will see what's happening. Thanks guys ✌️

Similar issue with .instanceOf:

propTypes = {
  date: PropTypes.instanceOf(Date),
}

Should I open another issue for this?

[emersonlaurentino]

@albinekb the problem is similar, so i believe we can keep it here.

these also have the same problem:

propTypes = {
  optionalMessage: PropTypes.instanceOf(Message),
  optionalEnum: PropTypes.oneOf(['News', 'Photos']),
  optionalUnion: PropTypes.oneOfType([
    PropTypes.string,
    PropTypes.number,
    PropTypes.instanceOf(Message)
  ]),
  optionalArrayOf: PropTypes.arrayOf(PropTypes.number),
  optionalObjectOf: PropTypes.objectOf(PropTypes.number),
  optionalObjectWithShape: PropTypes.shape({
    color: PropTypes.string,
    fontSize: PropTypes.number
  }),
}
