capabilities?format=json when using Authelia

[jjcasmar]

I am trying to configure Authelia as OIDC. I have managed to redirect OpenCloud to Authelia, authenticate and go back to OpenCloud.

My env vars for the the OpenCloud app are

      OC_OIDC_ISSUER: https://authelia.<domain>
      OC_EXCLUDE_RUN_SERVICES: idp
      PROXY_OIDC_REWRITE_WELLKNOWN: true
      PROXY_USER_OIDC_CLAIM: preferred_username
      PROXY_USER_CS3_CLAIM: username
      PROXY_AUTOPROVISION_ACCOUNTS: "true"
      GRAPH_ASSIGN_DEFAULT_USER_ROLE: "false"
      GRAPH_USERNAME_MATCH: none
      PROXY_ROLE_ASSIGNMENT_DRIVER: oidc 
      PROXY_ROLE_ASSIGNMENT_OIDC_CLAIM: groups
      PROXY_OIDC_ACCESS_TOKEN_VERIFY_METHOD: none
      IDP_ISSUER_URL: https://authelia.<domain>
      IDP_DOMAIN: <domain>
      WEB_OIDC_CLIENT_ID: opencloud-web

and in proxy.yml I have configured the correct mappings

role_assignment:
  driver: oidc
  oidc_role_mapper:
    role_claim: groups
    role_mapping:
      - role_name: admin
        claim_value: admins
      - role_name: spaceadmin
        claim_value: opencloudSpaceAdmin
      - role_name: user
        claim_value: opencloudUser
      - role_name: guest
        claim_value: opencloudGuest

However, when I login with Authelia, I get a 500 error when accessing <domain>/cloud/capabilities?format=json.

If I visit that url directly, I get a proper json with the following content

Do I need to set something else?
