Research direction

Start with the examples and the Collapse and Panel entry points, then reproduce the build using React 16.6.3 and the Create React App stack. Trace the Collapse import or export that produces the undefined element and verify that the example renders without the error while Panel still works.

Written by the indexing model from the issue text.

Description

Following along with the examples, using Collapse triggers this error in my build:

Invariant Violation: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports. Check the render method of `ComponentName`.

Replacing Collapse with nothing or a string clears up the error. Panel export is fine.
