Element type is invalid

[geowa4]

Describe the bug When I try to load the SlateTranscriptEditor component, I receive the following error.

Uncaught Error: 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 `SlateTranscriptEditor`.

The above error occurred in the <button> component:
    in button (created by Button)
    in Button (created by SlateTranscriptEditor)
    in RefHolder (created by OverlayTrigger)
    in OverlayTrigger (created by SlateTranscriptEditor)
    in div (created by Col)
    in Col (created by SlateTranscriptEditor)
    in div (created by Row)

    in Connect(TranscriptEditor) (created by Route)
    in Route (created by App)
    in div (created by App)
    in Router (created by ConnectedRouter)
    in ConnectedRouter (created by App)
    in div (created by App)
    in App (created by Route)
    in Route
    in Router (created by BrowserRouter)
    in BrowserRouter
    in Provider

To Reproduce All I've done is drop in this snippet.

<SlateTranscriptEditor
  mediaUrl={videoURL}
  transcriptData={transcript}
  handleSaveEditor={() => this.save()}
/>

Expected behavior N/A; see screenshot

if you got time, it be useful to try on a new Create React App, and import STE there, and see if that works?

This turned out to be a dependency problem with fonts. Oy

Thanks for taking our questions in DMs!
