Trying to get a simple tile map working in a webpack project and keep getting this:

Cannot read properties of undefined (reading 'length')
TypeError: Cannot read properties of undefined (reading 'length')

Is that enough of a clue for someone here to see what the issue is? Alternatively, is there any recent bare-bones example project available I can crib from? The one pointed to in the docs is pretty out of date so I've been trying to lift out what I need from it into a new project, but so far no go.
