Helm chart from `main` as of 2025-08-11 is not compatible with 1.0.x binaires (provides incorrect defaults)

https://github.com/apache/polaris/blob/bae5444cf37ef86a2c472ded33c513dff3350053/helm/polaris/values.yaml#L567

`type` for both `authenticator` and `roleProvider` should be one of `internal`, `external`, or `hybrid`. `default` is not accepted by polaris itself

Start at helm/polaris/values.yaml around line 567 and compare the authenticator and roleProvider defaults with the accepted Polaris 1.0.x values stated in the issue. Done means the chart supplies only compatible defaults for both settings; verify the rendered chart values if the repository provides a Helm validation path.
