hook, skipping...
java.lang.NullPointerException
	at org.jenkinsci.plugins.github.webhook.subscriber.DefaultPushGHEventSubscriber.onEvent(DefaultPushGHEventSubscriber.java:79)

I find out that in https://github.com/jenkinsci/github-plugin/blob/master/src/main/java/org/jenkinsci/plugins/github/webhook/subscriber/DefaultPushGHEventSubscriber.java#L76
URL repoUrl = push.getRepository().getUrl();
https://github.com/hub4j/github-api/blob/main/src/main/java/org/kohsuke/github/GHObject.java#L98-L100

public URL getUrl() {
        return GitHubClient.parseURL(url);
}

https://github.com/hub4j/github-api/blob/main/src/main/java/org/kohsuke/github/GHObject.java#L31
private String url;

it is trying to get url data from payload object of GHRepository

https://github.com/go-gitea/gitea/blob/main/modules/structs/repo.go#L50-L110
but in Repository struct there don't have any url variable
I test it adding the variable and it's now not showing NullPointerException on jenkins server.
