That's because the event code not entered doesn't exist or is otherwise invalid.

There's a checksum built into the string of letters so attempts to iterate them can be rejected without loading the database.

 

Neat, I didn't know that. What's the checksum?

Essentially just ID + SHORTHASH(ID, SECRET). So it's not so much a checksum as it's a signature. Just a very small one.

Ah, so you're not validating Eventlink codes; you're just checking whether it's a code that someone has made an event for on decklist.lol. I see.

Correct!

Eventlink, unfortunately, offers no way it integrate with it at all.
