Roblox website cannot handle asset URLs containing Windows reserved words (HTTP 400)

Roblox website cannot handle the words CON, PRN, AUX, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, and LPT9 in any URL path without redirecting to a 400 bad requests page.

It occurs 100% of the time.

Repro steps:

  • Go to develop.
  • Create a T-Shirt, game or any asset and use some of the words above as the name.
  • Try going to the item’s page.
  • It will redirect to bad request error page.

Example: https://www.roblox.com/games/4645633008/CON.

All of those broken names are reserved on Windows.

No, all Windows reserved names are broken.

does lua go through windows ?
or have windows based extentions that would have the need for this to be here ?
could it be because of what the framework of roblox was based on ?
does windows have operations related to the links in such a way ?

also, does this happen on a non windows computer ?
is it consistent on all browsers ?
or what about reserved words on other OS ?

Happens on my Android smartphone too. As far as I know Android == Linux

Hello,

I have found out that some specific keywords can make page inaccessible.
The keywords I have found are nul and aux .

Example
https://roblox.com/nul / https://roblox.com/aux
Both of these redirect you to https://www.roblox.com/request-error?aspxerrorpath=/.

This is a problem when it comes to naming assets since they will become inaccessible to edit.
I renamed one of my non-important models to nul to showcase this: https://www.roblox.com/catalog/4641032440/nul

You can still access the model in studio but you have no way to view its page.

People have recently started using this to hide malicious scripts.

This issue should be fixed now. For example, if you search for ‘aux’ in the library, the link will show up as https://www.roblox.com/catalog/4641032440/unnamed
