# X_PRELOAD_UNKNOWN_RELATION

## Means

no relation of that name on this entity

## Typical cause

a typo, or a relation the schema never declared — relations are derived from `references()` columns, so there is no list to read them off

## Fix

the `fix` is a call on one that exists, e.g. `relationNamed('posts', 'author')   # or: org, likes`. No foreign key at all ⇒ `x entities list --json`, then add `.references(() => <target>.id)` to the column that points at one
