Excalidraw: Cannot Read Length When Opening File

[acafourek]

Today, when attempting to open two Excalidraw exports, I would select the file locally and click "open" in the browser dialog and see a console error of actionExport.tsx:82 TypeError: Cannot read property 'length' of undefined and the file does not load to the UI.

The exports were generated from the site sometime 3-5 weeks ago and a local parser confirmed that they are valid JSON

Perhaps related to #632?

Full console error:
