What did you expect to happen:

• The plugin to be able to connect to the engine.

How do we reproduce it?

Just follow the getting started in the readme for the hobby environment : https://github.com/grafana/oncall?tab=readme-ov-file#getting-started

1. Download the docker compose file :

curl -fsSL https://raw.githubusercontent.com/grafana/oncall/dev/docker-compose.yml -o docker-compose.yml

2. Set variables :

echo "DOMAIN=http://localhost:8080
# Remove 'with_grafana' below if you want to use existing grafana
# Add 'with_prometheus' below to optionally enable a local prometheus for oncall metrics
# e.g. COMPOSE_PROFILES=with_grafana,with_prometheus
COMPOSE_PROFILES=with_grafana
# to setup an auth token for prometheus exporter metrics:
# PROMETHEUS_EXPORTER_SECRET=my_random_prometheus_secret
# also, make sure to enable the /metrics endpoint:
# FEATURE_PROMETHEUS_EXPORTER_ENABLED=True
SECRET_KEY=my_random_secret_must_be_more_than_32_characters_long" > .env

3. Launch services:

docker-compose pull && docker-compose up -d

4. Connect to grafana : login to http://localhost:3000 with admin/admin

5. Enable the grafana oncall plugin and try to connect it to the backend at the address http://localhost:8080
