Return Results from context.run - Upstash Documentation

Always return step results if needed in subsequent steps.

export const { POST } = serve<string>(async (context) => {  const input = context.requestPayload  let result  await context.run("step-1", async () => {    result = await someWork(input)  })  await context.run("step-2", async () => {    await someOtherWork(result)  })})

export const { POST } = serve<string>(async (context) => {  const input = context.requestPayload  const result = await context.run("step-1", async () => {    return await someWork(input)  })  await context.run("step-2", async () => {    someOtherWork(result)  })})

@serve.post("/api/example")async def example(context: AsyncWorkflowContext[str]) -> None:    input = context.request_payload    result = None    async def _step_1() -> Dict:        nonlocal result        result = await some_work(input)    await context.run("step-1", _step_1)    async def _step_2() -> None:        await some_other_work(result)    await context.run("step-2", _step_2)

@serve.post("/api/example")async def example(context: AsyncWorkflowContext[str]) -> None:    input = context.request_payload    async def _step_1() -> Dict:        return await some_work(input)    result = await context.run("step-1", _step_1)    async def _step_2() -> None:        await some_other_work(result)    await context.run("step-2", _step_2)

Because your workflow endpoint is called multiple times, result will be uninitialized when the endpoint is called again to run step-2.

If you are curious about why an endpoint is called multiple times, see how Workflow works.
