chaosmonkey can not find eligible instances to terminate

Issue Description

When I tried to terminate instances using this command: chaosmonkey terminate my-chaosmonkey-app default

"my-chaosmonkey-app" is my application name
"default" is the account name

I got this error:

[57965] 2025/03/09 00:04:03 WARNING: eligible.Instances failed for InstanceGroup{app=my-chaosmonkey-app account=default region= stack= cluster=}: Name 'deployment my-chaosmonkey-app' does not have any labeled or unlabeled matches
[57965] 2025/03/09 00:04:03 No eligible instances in group, nothing to terminate: InstanceGroup{app=my-chaosmonkey-app account=default region= stack= cluster=}

Chaosmonkey is running on my macOS, cloud provider is Kubernetes, and the Spinnaker is managed by Halyard on docker.

Here are some information of the deployments:

The configuration of the monkey for the application is also valid:

The chaosmonkey.toml:

[chaosmonkey]
enabled = true
schedule_enabled = true
leashed = false
accounts = ["default","spinnakerk8s"]
region = "us-west-2"

start_hour = 9      # time during day when starts terminating
end_hour = 15       # time during day when stops terminating

# location of command Chaos Monkey uses for doing terminations
term_path = "./chaosmonkey-terminate.sh"

# cron file that Chaos Monkey writes to each day for scheduling kills
cron_path = "./cron.d/chaosmonkey-schedule"

[database]
host = "127.0.0.1"
name = "chaosmonkey"
user = "root"
encrypted_password = "root"

[spinnaker]
endpoint = "http://127.0.0.1:8084"

And information about my Spinnaker: This is the application:
