Access value from form data from request parameter in express js

Project: Codever - File: user.router.js The values are present in the request.body which contains key-value pairs of data submitted in the request body. In our case we access the userDisplayName with the following expression request.body.userDisplayName as in the example below:

usersRouter.post('/:userId/bookmarks/upload', keycloak.protect(),
  uploadBookmarks.single("bookmarks" /* name attribute of <file> element in your form */),
  async (request, response) => {
    userIdTokenValidator.validateUserId(request);

    const userDisplayName = request.body.userDisplayName;
    const importResponse = await browserBookmarksImportService.imporBrowserBookmarks(request.params.userId, request.file.buffer, userDisplayName);

    const str = JSON.stringify(importResponse, null, 2); // spacing level = 2
    console.log(str);

    return response.status(HttpStatus.OK).send(importResponse);
  }
);

In angular the userDisplayName value has been appended to the FormData and submitted to a post request via the Angular Http Client:

  uploadBookmarks(userId: String, bookmarks: File, userDisplayName: string): Observable<any> {
    const formData = new FormData();
    formData.append('bookmarks', bookmarks);
    formData.append('userDisplayName', userDisplayName);

    return this.httpClient.post(`${this.usersApiBaseUrl}/${userId}/bookmarks/upload`, formData);
  }
