Research direction
Read src/sdk/builders/tasks/index.ts and the task-builder exports first. Add src/sdk/builders/tasks/exclusiveJoin.ts following the proposed signature and fields, then export exclusiveJoinTask from the index; done means the EXCLUSIVE_JOIN builder is reachable through the SDK API.
Written by the indexing model from the issue text.
Description
Summary
TaskType.EXCLUSIVE_JOIN is in the enum but there is no exclusiveJoinTask() builder.
The defaultExclusiveJoinTask field is unreachable via the SDK API.
Server baseline
Conductor 3.32.0-rc.9
Evidence
Static: TaskType.EXCLUSIVE_JOIN exists in types.ts:61; no builder exported from
builders/tasks/index.ts.
Live (2026-07-16): A raw EXCLUSIVE_JOIN task inside a SWITCH workflow was registered
and executed against Conductor OSS 3.32.0-rc.9. Workflow completed successfully — gap is SDK-only.
Proposed fix
Add src/sdk/builders/tasks/exclusiveJoin.ts:
import type { WorkflowTask } from "../../../open-api";
import { TaskType } from "../../../open-api";
export const exclusiveJoinTask = (
taskReferenceName: string,
joinOn: string[],
defaultExclusiveJoinTask?: string[],
optional?: boolean
): WorkflowTask => ({
name: taskReferenceName,
taskReferenceName,
type: TaskType.EXCLUSIVE_JOIN,
joinOn,
defaultExclusiveJoinTask,
inputParameters: {},
optional,
});
Export from builders/tasks/index.ts.
