Error: Something went wrong. Could not fill variables in: (undefined) undefined

[kper]

Code:

var test = 3165;

wiki()
    .findById(test)
    .then(page => {
        console.log(page);
        page.mainImage().then((img) => {
            console.log(img);
        });
    });

Output:

Fixed in v4.3.4

The issue was in the info box parser. The parser was failing on one field, and giving up. Instead I now return undefined for the problem field and return whatever else we can parse.

Should fix many issues I think.
