NodeJS - TypeError: Busboy is not a constructor

Question

So, something happened a couple of days ago and a project of mine started showing the following error:

TypeError: Busboy is not a constructor

What I think is strange is that this Busboy isn't being used on my code, only in dependencies from node_modules. Does anyone know if there is any compatibility error with the version of Busboy or any of those listed in the error that could cause such thing?

Answer 1

Busboy exports a function and not a class. So, one need not use new keyword for creating an instance of Busboy.

const Busboy = require('busboy');
const busboy = Busboy({ headers: req.headers });
