A bunch of records cannot be deleted using applyWrites: get HTTP 500 in return

[imax9000]

I have a number of records that applyWrites fails to delete. When they appear in a request with other writes, the whole request fails (obviously). They also fail to get deleted when sending just one write.

All of them are currently live, as in getRecord successfully returns them.

Did not try to delete them using deleteRecord in case that succeeds - so you have specimens to use for debugging.

File with record URIs: stuck-records.txt

Will try other ways to delete them in the next couple days.

deleteRecord and putRecord also don't work.

putRecord with the identical content succeeds, but probably only because it compares the content before writing. If I change any bit of the record - it also fails with 500.

It seems like these records ended up in a shard(s) that became read-only at some point, and there's no mechanism to move them off that shard.
