DBX JS SDK via Access Token not working for multiple users

Sure!

So I'm building a widget using Kendo for VUE/jQuery ((they are rather interchangeable between their many flavors)). This front-end component serves as a way for a user to access a particular drop box folder in my console-drop box-app. This is facilitated by a NodeJS back-end, which I've published some of the code for below.

class DropboxWidgetsService extends BaseService {
    constructor(stash, log) {
        super(stash, log);
        this.dbx = new Dropbox({ accessToken: process.env.DROPBOX_ACCESS_TOKEN });
    }
​
        async getDropboxFolderFiles(code, step) {
        try {
            let data = await this.dbx.filesListFolder(
                {
                    'path': `/magic-location/${code}/${step}`,
                    'recursive': true
                }
            );
            return data.result.entries.filter(el => el['.tag'] === 'file');
        } catch (error) {
            this.log.debug(error);
        }
    }

      async createDropboxWidgets(req, res) {
        try {
            let fileSaveLocation = __dirname.slice(0, __dirname.indexOf('services')) + 'temp';
            let magicalProjectCode = req.query.magicalProjectCode;
            let magicalProjectStep = req.query.magicalProjectStep.toUpperCase();
            console.log('projectStep', magicalProjectStep);
            let file = req.files[0];
            //TODO: We will want to include file type limiters based on the project step.
            let originalName = file.originalname;
            let buffer = file.buffer;
            let location = fileSaveLocation + '\\' + `${originalName}`;
            await fs.writeFile(location, buffer, async (err) => {
                if (err) {
                    this.log.debug(err);
                    return;
                }
                let response = await this.dbx.filesUpload({
                    path: `/Hogwarts/${magicalProjectCode}/${magicalProjectStep}/${file.originalname}`,
                    contents: fs.createReadStream(location)
                });
                await fs.unlink(location, (err) => {
                    if (err) {
                        console.error(err);
                        return;
                    }
                });
                res.json({status: response.status, path: response.result.path_lower});
            });
            
        } catch (error) {
            this.log.debug(error);
        }
    }
}
