Getting error with rasa-oss helm install

hey guys, could you pls support me deploying a rasa-oss instance?

I’ve prepared k8s cluster, kubectl and helm according to the docs

then I’ve copied values.yml from github repo

now I’m deploying:

$ helm install \
>     --generate-name \
>     --namespace adaptis \
>     --values rasa-oss-values.yml \
>     rasa/rasa

and finally got the following error:

Error: parse error at (rasa/templates/nginx-tls-secret.yaml:2): function “genSelfSignedCertWithKey” not defined

Would you be so kind to explain me how to overcome? Great thanks

I think you shouldn’t fetch an URL. Just use the name you would pass to helm install.
