Error while creating ingress "googleapi: Error 400: Invalid value for field 'namedPorts[0].port"

[rsff]

When trying the helm examples instead of using the proxy and the port forward I would like to expose them to a LB, the problem is when I try to expose them the following happens:

test) kubectl get svc --namespace jenkins

the svc needs to be NodePort type.
