A user of the Integration Starter Kit reported having issues with the default docker-compose.yaml when using the otel/opentelemetry-collector-contrib:latest image. Currently the latest tag seems to forbid the usage of the Loki exporter in the OpenTelemetry Collector config file. It gives the following error:
We need to investigate what happened in the latest images of the OpenTelemetry Collector for this to not be compatible anymore. For now, reverting to otel/opentelemetry-collector-contrib:0.113.0 seems to fix the issue.
