I was really impressed with Scavenger on Naver Deview 2023! So, I tried to use it myself, but I ran into a problem.

When I run scavenger-agent after running scavenger-collector and scavenger-api manually, I always get the same error. what is the problem..?🥲

UNAUTHENTICATED seems to be related to #23.
Can you check it out?

@jcw1031 Hello :)
Firstly, can you tell me what commands you ran the collector and api with?
Also, could you please share your scavenger configuration as well.

Can you change scavenger.collector-server-url from http://localhost:9090 to http://localhost:8080?
Additionally... The guide is confusing, I'll fix that.
