Hello!
I created an OAuth app. After installing it, I got the authorization code.
Using this authorization code, I was able to get OAuth token at the first try. See the following logs.
2020-06-05 20:07:45.163 INFO 74688 --- [ scheduling-1] c.o.o.e.n.q.i.s.p.ActivityMeetingProcess : Get Zoom OAuth: https://zoom.us/oauth/token?grant_type=authorization_code&code=olsDh8lp8w_yhMUmzNeQkyqlte7Etc8Bw&redirect_uri=https:/myredirecturl

After one minute, I use the same authorization code and try to get a new OAuth token. However, I got 400 with “Invalid authorization code”

No matter how many times I tried, with this authorization code, I got the same error. I didn’t reinstall the app to generate a new authorization code.
Could you explain to me why this happen? Thank you.
