**Steps to reproduce** - Save an empty object `{}` in NewcomerTasks.json or GrowthExperimentsConfig.json - Run the migration script from T359038 **What happens** Config is migrated setting all configs defined by providers as an empty array `[]` That's because CommunityConfiguration\Store\WikiPage\Writer calls `$configSorted = get_object_vars( $newConfig );` to sort config options which returns an array, then passed to `FormatJson::encode( $configSorted )`. When the update is an empty object and $configSorted an empty array the encoding will result in a wrong empty array at the top level of the config. **What should happen instead** Config is migrated setting all configs defined by providers as an empty object `{}`
