React uncaught error fail to get ".page__content" element

Question

I was developing in react, and all of the sudden, I get fail to get ".page__content" element..

Googling yielded nothing.

Happened after I added <Text>Or:</Text>.

Using React 15.0.2.

What the error means?

Answer 1

Apparently, I hope one of the ReactJS developers can explain why, this error message happens when you use a built-in React Native component that doesn't exist (since we're not using react native here).

If you forget to use the capital letter, effectively using a non existing component <asdf>Or:</asdf> nothing happens (weird! no error message?!).

I checked with another built-in component <Image>Or:</Image>, it generated the same error message.

Also, a tip, if you're using a UI framework that supports react, be very careful of components, if, for example, one uses Onsen UI, and does <Page>Or:</Page>, the Page component takes over the whole page, so be careful with components!
