`SOCIAL_AUTH_BACKEND_ATTRS` in `extraConfig`: Pod Crash

[t0mcat1337]

The Helm chart version

netbox-7.1.17

Environment Versions

Kubernetes: 1.33.5
Helm: 3.18.4

Custom chart values

remoteAuth:
  enabled: true
  backends:
    - social_core.backends.keycloak.KeycloakOAuth2
[...]
extraConfig:
  - values:
      SOCIAL_AUTH_KEYCLOAK_AUTHORIZATION_URL: '<keycloakAuthURL>'
      SOCIAL_AUTH_KEYCLOAK_ACCESS_TOKEN_URL: '<keycloakTokenURL>'  
      SOCIAL_AUTH_KEYCLOAK_SECRET: '<keycloakSecret>'
      SOCIAL_AUTH_KEYCLOAK_PUBLIC_KEY: '<keycloakKey>'
      SOCIAL_AUTH_KEYCLOAK_ID_KEY: 'email'
      SOCIAL_AUTH_KEYCLOAK_KEY: 'netbox'

Current Behavior & Steps to Reproduce

With the above values.yaml snippet I managed to let netbox use keycloak as an auth backend, which works fine.
Now for a little cosmetics I wanted to customize the "Keycloak" Login Button as described here (https://netboxlabs.com/docs/netbox/administration/authentication/overview/#single-sign-on-sso) in the netbox docs at the very end.

So I figured out the following seems to be the only form of writing "SOCIAL_AUTH_BACKEND_ATTRS" correctly, so that at least the config parser ("configuration.py") accepts it:

extraConfig:
  - values:
      [...]
       SOCIAL_AUTH_BACKEND_ATTRS: '{"keycloak": ("My Custom Name", "login")}'

But after that the container nevertheless crashes with the Exception below.

Expected Behavior

Let use "SOCIAL_AUTH_BACKEND_ATTRS" parameter correctly for customizing the OIDC Login Button when using Keycloak for example.

Thanks for filing this issue, @t0mcat1337.

extraConfig:
  - values:
      [...]
       SOCIAL_AUTH_BACKEND_ATTRS: '{"keycloak": ("My Custom Name", "login")}'

Such values must be escaped; otherwise, they are interpreted as dictionaries by Helm.
