Trying to fill a pdf and everything works great except the checkboxes. When using
const checkbox = form.getTextField('checkbox1')
checkbox .check();

Error Message:
[email protected]:15 Uncaught (in promise) Error: Expected field "checkbox1" to be of type n, but it is actually of type e

const checkbox = form.getCheckBox('checkbox1')
checkbox .check();
