This is my code that was working correctly:

import { format, parse } from "date-fns";

///irrelevant code

export class Task {
    constructor(name, notes, dueDate, priority, taskId = uuidv4()) {
        this.name = name;
        this.notes = notes;
        this.dueDate = "Due: " + format(parse(dueDate), "MM/dd/yyyy");
        this.priority = priority;
        this.taskId = taskId;
    }
}

Now, suddenly, I’m getting an error in the console, as seen in the image.

I’ve tried reinstalling date-fns with npm and switching it to the DevDependencies in package.json. It works fine if I just remove the format, but I’m puzzled because it was working fine earlier. I did not make any changes to anything.
