word property undefined in conjugate results

[delesslingw]

Trying out the library and unfortunately the conjugate method returns an array of objects with word properties that equal undefined. In this example I'm using andar but it seems to happen for every verb I try.

My code:

const {translate, conjugate} = require('sdapi').default

translate('libro').then(console.log);

conjugate('andar').then(res => res.filter(entry => entry.paradigm === "presentIndicative")).then(console.log)

Console:
