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

I'm getting almost the same error:

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

I was trying to import a pure functional component from another node library my team has developed. To fix it, I had to change to an absolute import (referencing the path to the component inside node_modules) from

import FooBarList from 'team-ui';

to

import FooBarList from 'team-ui/lib/components/foo-bar-list/FooBarList';
