Error 500 When Trying to Access Dropbox Api via Dropbox Sdk

I have an app that via Dropbox Javascript SDK trying to download the file. I don't have any idea what is wrong. Accessing Dropbox API via fetch calls directly bringing the same error.

const Dropbox = require("dropbox").Dropbox;
import axios from "axios";
import { logger } from "./logger";

export class FileHandler {
    public async handle(path: string, token: string): Promise<void> {
        try {
            const dbx = new Dropbox({ fetch: axios, accessToken: token });
            dbx.filesDownload({ path })
                .then((data) => {
                    console.log(data);
                })
                .catch((error) => {
                    logger.error(error);
                });

        } catch (err) {
            logger.error(err);
        }
    }
}

Error is the follow:
