Having Trouble Setting the Title and Description in Plone Classic UI

Good morning everyone,

I am in the process of preparing a classic Plone addon to function within the Volto CMS. However, I am running into an issue with setting the Title and Description. Whenever I try to submit new content, I get the following error in the python console:

2022-04-18 10:42:46,708 ERROR   [Zope.SiteErrorLog:35][waitress-0] ValueError: http://localhost:3000/admissions-new/POST_application_json_

I am currently running Plone 5.2.6 (backend) with Volto 15.4.1 (frontend).

What should I do to ensure that this addon is compatible in Volto? Would I need to adjust the python code at all? Or is it mostly a frontend issue in Volto where I must change the code there?

I thank you kindly.

Sincerely,
