Just tried those links and got the same. Internal error.
Think it worth putting in a support ticket for that.

Yes, I'm still receiving the same error for about four clubs in my list - I'll report it.
That's out of 49 endpoint requests, so it's affecting only a small proportion but still annoying.

Seems it's not the only problem. https://api.chess.com/pub/club/team-usa/matches
This one doesn't return the registered matches.

My last reply from staff was on 19/April when they were checking with the developers to see what the problem is & if there's a 'workaround' for it. I assumed that they'd simply try to fix it?
Nothing since then.
Oh, you got answers from them?! Cool. They never answer on my bug reports. Maybe it is a positive tendency and we can hope for a fix earlier than in a half of year.

Ah, yes but only because I've given up bothering with reporting problems via the site - I now send emails instead and it seems to work much better.

It's been ten days now and the problem still persists and I havn't received any reply to my original complaint.
Not a good look?
I've been getting back a few 500 HTTP error codes for a number of club match archive endpoint requests in the last hour. The code is for a generic server error issue but I'm wondering what the underlying problem is?
These are some of the endpoint requests that are returning that code:-
https://api.chess.com/pub/club/the-netherlands/matches
https://api.chess.com/pub/club/hampovsky-chess-club/matches
https://api.chess.com/pub/club/motorhead/matches
All I get is "{"status":"error","message":"Internal Server Error"}"
Anyone else encountering this?
