Some users' timelines show "Unsupported feature" page

[irauta]

Opening the page at https://nitter.net/intenttoship shows an "Unsupported feature" page instead of the expected user timeline/profile page.

The user's individual tweets can be opened, for example https://nitter.net/intenttoship/status/1636087416959258625 works - I first encountered the user through that individual tweet on another user's timeline RSS feed with no hint of anything being wrong.

I don't know much of Nim or the routing system used by Nitter, but I have a hunch this happens because the "/intent/?@i?" route in unsupported.nim maybe has a higher priority than the route that would show the user profile. I found some other cases with the user search that show the same behavior:

https://nitter.net/intentcompany
https://nitter.net/intentdatasci

However, this one does work:

https://nitter.net/Intent_blog

Seems like only lower case "intent" causes this. This proved out to work as a workaround: capitalize a letter in the "intent" part of account name, and the profile opens, as Twitter usernames apparently are case-insensitive. For example, the address https://nitter.net/Intenttoship works.

Looking at unsupported.nim, there's also the route "/login/?@i?", which made me suspect that usernames starting with "login" might also be affected, and this seems to be the case. For example https://nitter.net/logindotgov also causes the "Unsupported feature" page. Capitalizing the first letter (or any letter in "login" I suppose) shows the profile page, as with "intent" users. I did not try to check the other path patterns, as they didn't seem suspicious.

@zedeus It would be better to move

nitter/src/nitter.nim

Line 93 in bc219aa

extend unsupported, ""

to the end of routes which makes it a literally catch-all.

@jackyzy823 thanks, but that breaks several routes like settings and search since timeline swallows them. I used your suggestion and added a fix that makes the routing order less important: 91c6d59
