# X_TENANCY_ACTOR_MISMATCH

## Means

a call named a tenant other than the actor's — as a query predicate, or as the tenant column of a row being written

## Typical cause

an `orgId` that arrived as action input, a query string or a path parameter, passed into a repo call; or an `insert`/`upsertAll` row, or an `update` patch, naming another tenant — the cause names both tenants

## Fix

drop the `orgId` argument, the actor's tenant scopes the plan; or act as that tenant with `withChildContext({ actor })`; a read that must span tenants is `crossTenant('<why>', fn)`
