[keycloak-user] Exception with User Storage SPI priority configuration

Hi,

I just tested and investigated a bit more…

When saving a UserStorageProvider, the „priority“ value is sent within the config object:
{
  "id": "320db9e2-6c40-4eb5-868e-95717be36fce",
  "name": "my-user-storage",
  "providerId": "my-user-storage",
  "providerType": "org.keycloak.storage.UserStorageProvider",
  "parentId": "demo",
  "config": {
    "baseUrl": [
      "http://localhost:9000"
    ],
    "basicAuthUsername": [
      "admin"
    ],
    "basicAuthPassword": [
      "secret"
    ],
    "priority": {
      "0": "1"
    }
  }
}

In contrast to a UserFederationProvider, where the „priority“ value is sent as part of the root object, not in the nested config object.

When adding a „priority“ config property in my UserStorageProvider, it works, but it looks strange in the Admin console, as there are now 2 priority fields… but it works.

Additionally, this error with the priority value leads to some JS error messages in the browser console when working with the Admin console. These are also gone when using an own „priority“ config property.

I’d appreciate any feedback on this, if this is an error or whatever…
Thanks!

Regards,
- Niko
