Hello, I'm running K8S v1.15.12 and Adapter v0.10.0. I have next error:
selectors:
I0413 13:51:41.576749 1 client.go:52] using AWS Region: request blocked by whitelist-route-regexp "'.'": /latest/meta-data/placement/availability-zone/

Main points:

1. I can't understand why is it blocking .* regex pattern of kiam whitelist-route-regexp
2. is the MissingEndpoint endpoing related to path of kiam
3. when I run Adapter v0.8.0. everything works(AWS creds injected via env. variables, assume role is also did'nt worked for me)

some updates so far

1. for test purpose use kiam --whitelist-route-regexp=.* (without quotes)
2. Don't use hiphens in queries id of ExternalMetric - External metrics API: ValidationError #2
