OK - I re-did the steps described earlier and now get the following error message:
ready - started server on 0.0.0.0:3000, url: http://localhost:3000
event - compiled client and server successfully in 620 ms (149 modules)
Error: You cannot define a route with the same specificity as a optional catch-all route (“/” and “/[[…catchall]]”).

UPDATE: Removing all my local pages after pushing to github and using Plasmic’s catchall now works as expected. Going forward, I just simply turn off pushing to github repo so that I can continue to edit pages via Plasmic’s UI and let local code pull latest changes.
