Helm template fails when knative serving is enabled

[andcan]

It's not possible to render with helm template:

wrote generated/openfunction/crds/builder.yaml
wrote generated/openfunction/crds/clustereventbus.yaml
wrote generated/openfunction/crds/eventbus.yaml
wrote generated/openfunction/crds/eventsource.yaml
wrote generated/openfunction/crds/function.yaml
wrote generated/openfunction/crds/gateway-api.yaml
wrote generated/openfunction/crds/gateway.yaml
wrote generated/openfunction/crds/serving.yaml
wrote generated/openfunction/crds/trigger.yaml
wrote generated/openfunction/charts/dapr/crds/components.yaml
wrote generated/openfunction/charts/dapr/crds/configuration.yaml
wrote generated/openfunction/charts/dapr/crds/resiliency.yaml
wrote generated/openfunction/charts/dapr/crds/subscription.yaml
Error: open generated/openfunction/charts/knative-serving/crds/serving.yaml: no such file or directory

Reproduction steps:

helm repo add openfunction https://openfunction.github.io/charts/
helm repo update
helm pull openfunction/openfunction
tar zxf openfunction-v0.8.1-v0.4.0.tgz
cd openfunction
helm template . --include-crds --output-dir generated

The error occurs when including crds and specifying the output directory. This commands do not make helm template fail:

helm template . --output-dir generated
helm template . --include-crds
helm template . --include-crds --output-dir generated --set global.KnativeServing.enabled=false
