Element type is invalid: expected a string (for built-in components) or a class/function

I just got the following issues when making a simple link. when removing the link the error will disappear:

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

<Link route="product" params={{ slug: "a-product-url" }}>
    <a>Product link!</a>
</Link>

Probably you have import Link from '../routes' Try to use import { Link } from '../routes' instead
