I had one of those matches too but I think the staff must have corrected your one already because it's changed to "status":"in_progress"
Bugs in Club Team Match

It's been 7-hours since your post.
When I click the example link:
- I see "board"
- I see "timeout_percent"
- Neither of which are an issue (IMO)
- I don't see "rating"
- I don't see "rd"
- Spec is outdated or wrong.
When I follow the "stats" (JSON-LD) URL for a player, I do see "rating" and "rd" for the variant or time-control. If the "rating" and "rd" should be frozen for a team mach, I don't see a problem. If they're revolving, then, just follow the (JSON-LD) stats link for the player, followed by the respective time control or variant. (As a temporary workaround. The Published API should be updated to reflect whatever change.)

Player ratings are given in matches with status "registration" but not "in_progress" & the match cited is now in the latter stage.
* I remember asking a few months ago for player ratings to be provided in matches "in_progress" & one of the developers made a favourable comment but it hasn't happened yet.

I think you are correct Stephen.
I was looking at the registration phase spec.
My code is now working again without mod. I suspect it was a time lag issue. When I ran the program yesterday it was just after the match had started. However I don't understand the "Closed" status. I can only assume there is an intermediate stage while the API updates from registration to in_progress.

Did you see the topic I started when this happened to me?

andreamorandini gave an explanation of what went wrong with the processing of the match. It's status seems to have been left 'hanging' as it progressed from registration to in-progress. That's two matches now within a week or so & I'm not sure if we're supposed to dismiss it as an anomaly or whether we need to provide for it in our scripts?
Two problems in end point https://api.chess.com/pub/match/{ID}
1)
status : closed.
This is not part of the specification.
2)
Items in red missing from player information
