Got `Server Error` when called API - `https://api.github.com/repos/apache/spark/pulls/27058/comments?per_page=100`

When we called https://api.github.com/repos/apache/spark/pulls/27058/comments?per_page=100&direction=asc&sort=updated , we got Server Error .
But if per_page is 50, it is 200.

It looks like a problem for the specific API:

apache/spark#27058 has 197 comments

$ curl -sSD/dev/stderr https://api.github.com/repos/apache/spark/pulls/27058/comments\?per_page=100 > /dev/null
HTTP/2 502 
server: GitHub.com
...

apache/spark#5694 has 406 comments

$ curl -sSD/dev/stderr https://api.github.com/repos/apache/spark/pulls/5694/comments\?per_page=100 > /dev/null
HTTP/2 200 
server: GitHub.com
...
