Steps to Reproduce: Reduced query + schema as much as possible. Simplifying anything eliminates the error.

update AuditLog set {
  cost := (
    (AuditLog.model.activePrice.dollar_price_per_thousand_prompt_tokens * <float64>AuditLog.rawModelResponse)
    +
    (AuditLog.model.activePrice.dollar_price_per_thousand_prompt_tokens * <float64>AuditLog.rawModelResponse)
  )
}

    single model: FoundationModel;
    cost: float64;
}

type FoundationModel {

        select .<FoundationModel[is FoundationModelPrice]
        limit 1
    );
}

type FoundationModelPrice {
