Proptypes validation of shape inside an array

[oswagner]

We have an array of objects and when try to validade the shape of the object inside that array, it seems to ignore that validation.

data: PropTypes.arrayOf(PropTypes.shape({
 someValue: PropTypes.bool
})

if we change PropTypes.bool in the sample above for PropTypes.potato, like below:

data: PropTypes.arrayOf(PropTypes.shape({
 someValue: PropTypes.potato
})

We don't receive any kind of message about the error.

For the latter, you wouldn't, because PropTypes.potato is undefined. Try specifying a propType that's actually invalid but exists, like PropTypes.number when it's a boolean?

@ljharb Sorry, but when I gave the example of PropTypes.potato. It refers if I try to change to any other type, the same problem occurs, even if I use something like PropTypes.number 😆

@oswagner see https://jsfiddle.net/69z2wepo/182882/ - I see a propType warning in the console, and when I change "number" to "string", it no longer shows an error.

Are you sure you're using the development build of React? The production build of react doesn't check propTypes.
