Error running endpoint example. #122

Hi, interesting. The error comes from this assert. So maybe, the bookkeeping of I hope that helps. It seems that your usage pattern : ... triggers the count to get out of sync. 😄 Unfortunately, I don't have time to dig into it but please feel encouraged to hunt the bug down yourself. It will be zig-educational 😄 |

I ran the endpoint example to play around with it for a while. I added a couple users. Deleted a few. Changed a few. However, When I tried to add another it crashed. Now sure why because I am just learning programming and am using zap as a learning tool due to my interest in REST servers.
Let me know if me creating this issue is not very useful or how I could present issue better.
