[Bug] Cannot read property '_links' of undefined

[iwfan]

It's failed when I first use this version-check action.

It looks like the problem is happening here

version-check/src/main.ts

Line 124 in ce272c9

(await request(eventObj.pull_request._links.commits.href))

Here is my Github action config file:

Hi, thanks for the report. I'm working on a rewrite so this will probably be solved by that. I hope I can finish it in the near future.
