# Don't Nest Context Methods

Avoid calling `context.call`, `context.sleep`, `context.sleepFor`, or `context.run` within another `context.run`.

<CodeGroup>

```typescript api/workflow/route.ts
import { serve } from "@upstash/workflow/nextjs"

export const { POST } = serve<string>(async (context) => {
  const input = context.requestPayload

  await context.run("step-1", async () => {
    await context.sleep(...) // ❌ INCORRECT
    await context.run(...) // ❌ INCORRECT
    await context.call(...) // ❌ INCORRECT
  })
})
```

```python main.py
@serve.post("/api/example")
async def example(context: AsyncWorkflowContext[str]) -> None:
    input = context.request_payload

    async def _step_1() -> None:
        await context.sleep(...) #  ❌ INCORRECT
        await context.run(...) #  ❌ INCORRECT
        await context.call(...) #  ❌ INCORRECT

    await context.run("step-1", _step_1)

```
