(See workarounds)\n\n# Patches  \nThis issue has been patched in `@keystone-6/core` version 6.5.2.\n\n# Workarounds  \nTo mitigate this issue in older versions where patching is not a viable pathway.\n\n- Set `{field}.isFilterable: false` statically for relevant fields to prevent filtering by them earlier in the access control pipeline (that is, don't use functions)\n- Set `{field}.graphql.omit.read: true` for relevant fields, which implicitly removes filtering by these fields your GraphQL schema",
