Uncaught Error: Invariant Violation: Element type is invalid: expected a string (for built-in components) or a class/function but got: object

Question

I am getting this error:

Uncaught Error: Invariant Violation: Element type is invalid: expected a string (for built-in components) or a class/funct

Answer 1

In my case I was using the default export, but not exporting a function or React.Component, but just a JSX element, i.e.

Error:

export default (
Hello World!
)

Works :

export default () => (
Hello World!
)
