Github Webhook With Jenkins return 302 Found

Question

I set up localhost jenkins, using ngrok to expose my jenkins to github. I didn't set up any credentials. When I test delivery from webhook, it shows 302 not found. Response:

Just got hit by the same issue. It appears that you are using the url: http://056b05cb.ngrok.io/github-webhook

Simply switch it to http://056b05cb.ngrok.io/github-webhook/ (notice the trailing /)

If you hit the url without the / on a browser, it will get a 302 and the browser will simply redirect. But the webhook does not follow redirects, so it simply tells you what the response was, which was a 302 redirect.
