Failed propType warning in v5.0.7

[cuongluu8]

I'm still getting the following warning in the console

Warning: Failed propType: Calling PropTypes validators directly is not supported by the `prop-types` package. Use `PropTypes.checkPropTypes()` to call them.

I'm using react 0.14.7

if I roll back to version 3.3.1 (before the prop-types dependency was added) this warning goes away.
This means the latest 5.x version is no longer compatible with v0.14.7?

You are trying to call one of the PropTypes validators - typeof PropTypes.string === 'function', but they are not supposed to be executed by you, but by a library. You need to check your code, the easiest way to do so would be just to put a breakpoint in the place of the warning and just trace back the actual function call which has caused it.

Done that - I'm pretty sure I am not doing that.
Also if I removed the autosize component then I do not get this warning

Could u share ur code on something like codesandbox.io then?

https://codesandbox.io/s/qxq8G1Gp
Inspect the console for the error/warning

Thanks for sharing, from what I see you should upgrade ur React version to v0.14.9 . More can be read here - facebook/prop-types#26

Yep - we'll probably upgrade to v15 in the future, but unfortunately we're stuck on 0.14.7 at the moment.

In the meantime u can try to upgrade to v0.14.9, it shouldnt bring any breaking changes and it will get rid of those warnings.
