Required field in JSON schema that can be oneOf: string, null, not handled correctly about helm HOT 3 OPEN

Can you create a more detailed replication example please. From a quick hack up using your jsonschema, if I use the values:

---
dummy:
  irsaRole: "foo"

I get the error:

 $ helm template .
Error: values don't meet the specifications of the schema(s) in the following chart(s):
jschema:
- dummy.irsaRole: Must validate one and only one schema (oneOf)
- dummy.irsaRole: String length must be greater than or equal to 20
- dummy.irsaRole: Does not match pattern '^arn:aws:iam:.+$'

Is there a subchart 'dummy'?

from helm.

@gjenkins8 apologies for the non-reproducible example. The real source for this issue is the k8gb Helm chart. I can also try to get you a more minimal example if you'd prefer.

from helm.

Steps to reproduce:

❯ git clone https://github.com/k8gb-io/k8gb && cd k8gb/chart/k8gb
❯ helm dependency build
❯ sed -i '' 's|arn:aws:iam::111111:role/external-dns|null|g' values.yaml
❯ helm install k8gb . --create-namespace -f values.yaml
Error: INSTALLATION FAILED: values don't meet the specifications of the schema(s) in the following chart(s):
k8gb:
- route53: irsaRole is required

from helm.
