Server Side Checks without Cloud Functions?

I have a Next Js Website where the Signed in Users can Come and Post.

There are only Certain days in a week which we allow the Users to Post like "You can Only Post on Tuesday".

And It works Good. But I Tried to Send a POST Request with Postman/Insomnia to the Appwrite server with a Different Date and Different Time like Changed the Date to a Year Before and It thought that It is TRUE and Created it on the Day I sent It.

Can I run any Server Side Checks to Fix this? I can't run Cloud functions because I'm using Kubernetes and It doesn't support it.

Any Help Would be Appreciated.

TL;DR

The user is experiencing an issue where they are able to bypass server-side checks by changing the date and time in a POST request to an Appwrite server. They are looking for a solution to prevent this but cannot use cloud functions due to using Kubernetes. No screenshots or further details are provided.

Hi - I am not sure about why it thinks as true, do you have any screenshots so I can take a look?

Hi,

This is the POST request.

Now I can change anything Like date & time

And it uses the Date & Time which gets from this Request
