Problem with GitHub Checks Api, webhook with empty .pull_requests array

Hello everybody, 

I have some troubles with webhooks from GitHub Checks.

When I create check_suite for old branch (or maybe for forks branch), iw got Webhook where . pull_requests array are empty. Also when i press “rerequest check suite” iw got the same thing, but you can see that pull request are here. 

https://github.com/GitAppTester/js/pull/2/checks

Event:

{
"action":"rerequested",
"check\_suite": {
"id":35572032,
"node\_id":"MDEwOkNoZWNrU3VpdGUzNTU3MjAzMg==",
"head\_branch":null,
"head\_sha":"caad24a1be06d00292e4f777b1767a4c18f566f5",
"status":"queued",
"conclusion":null,
"url":"https://api.github.com/repos/GitAppTester/js/check-suites/35572032",
"before":null,
"after":null,
"pull\_requests": [

    ],

What can be problem in?

Hey @npdev453,

Thank you for being here, I don’t see any obvious reason why this is happening. If you haven’t already, please contact us at git.io/c with the info so we can look into that further.

Best,

Andrea
