Those dependencies' versions need to be updated, please create a pull request in this repo with updated versions in Chart.yml.

Here is an example on where to find the newest chart version for Spark: https://github.com/bitnami/charts/blob/main/bitnami/spark/Chart.yaml

If that does not work, please include the full workflow you followed so anyone can reproduce the issue.

NB: you may want to update the Helm version you are using, should be 3.11
