[API reference](https://evolu.dev/docs/api-reference) › [@evolu/common](https://evolu.dev/docs/api-reference/common) › [Type](https://evolu.dev/docs/api-reference/common/Type) › SetItemsErrorValue

Defined in: [packages/common/src/Type.ts:13608](https://github.com/evoluhq/evolu/blob/bc4578a260dd15d5bbf94b83765ca05984d194cb/packages/common/src/Type.ts#L13608)

The shape of [SetItemsError](https://evolu.dev/docs/api-reference/common/Type/type-aliases/SetItemsError) and [SetElementsError](https://evolu.dev/docs/api-reference/common/Type/type-aliases/SetElementsError).

Structural issues are included only when `IncludeStructuralIssues` is true
because a typed boundary asserts the Set structure.

## Extends

- [`TypeError`](https://evolu.dev/docs/api-reference/common/Type/interfaces/TypeError)\<`"Set"`\>

## Properties

### reason

```ts
readonly reason: {
  issues: readonly [
     | true extends IncludeStructuralIssues ? SetExcessPropertyIssue : never
     | SetElementIssue<Error>,
     | true extends IncludeStructuralIssues ? SetExcessPropertyIssue : never
    | SetElementIssue<Error>];
  kind: "Items";
};
