# no-duplicate-step-id-in-workflow - ESLint plugin rules

This rule disallows invoking the same step more than once in a `createWorkflow` constructor without renaming the subsequent calls with `.config({ name })`.

## Severity

`error`. This rule is enabled in the [recommended](https://docs.medusajs.com/resources/lint#recommended) preset.

## What it Targets

This rule targets files in your project's `src/workflows` directory. It reports a step invoked more than once in a workflow's constructor when the duplicates aren't renamed.

The following code is reported by the rule:

```ts title="src/workflows/example.ts"
import {
  createWorkflow,
  WorkflowResponse,
} from "@medusajs/framework/workflows-sdk"

createWorkflow("hello", () => {
  const products = useQueryGraphStep({
    // ...
  })
  const customers = useQueryGraphStep({
    // ...
  })

  return new WorkflowResponse({ products, customers })
})
```

Instead, rename the subsequent calls with `.config({ name })`:

```ts title="src/workflows/example.ts"
import {
  createWorkflow,
  WorkflowResponse,
} from "@medusajs/framework/workflows-sdk"

createWorkflow("hello", () => {
  const products = useQueryGraphStep({
    // ...
  })
  const customers = useQueryGraphStep({
    // ...
  }).config({
    name: "fetch-customers",
  })

  return new WorkflowResponse({ products, customers })
})
```

## Why it's Important

Steps registered with the same ID throw an error at runtime. Giving each step a unique ID ensures the workflow runs correctly.

Learn more in the [Multiple Step Usages in Workflows documentation](https://docs.medusajs.com/learn/fundamentals/workflows/multiple-step-usage).

## Fixable

This rule is auto-fixable. Run the linter with the `--fix` option to apply the fix automatically.
