Just installed this package and tried to convert a board, and got this error:

/home/rob/tmp/node_modules/easyeda2kicad/dist/board.js:572
    var shapes = flatten(input.shape.map(function (shape) { return convertShape(shape, conversionState); }));
                                     ^

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