@connyay Cheers for the PR. Any chance you could add some tests for the ServiceMonitor? We must have missed them when adding it initially, this should help us avoid any issues going forward. Some examples can be found here

Yup yup. Will do.

More from our findings - if metrics.serviceMonitor.port is an integer it should really make it to a targetPort property on the service monitor.

Will work on some tests for this.

same with ArgoCD:

Failed sync attempt to bcb3d89bbd5cd5dc05f675c263dbcfe841486b00: one or more objects failed to apply, reason: error when patching "/dev/shm/3414896706": ServiceMonitor.monitoring.coreos.com "backstage" is invalid: spec.endpoints[0].port: Invalid value: "integer": spec.endpoints[0].port in body must be of type string: "integer"

currently this means OTEL integration is broken for some users
