# no-try-catch-in-workflow - ESLint plugin rules

This rule disallows `try/catch` statements directly inside a `createWorkflow` constructor or a `when().then()` callback.

## 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 `try/catch` statements placed directly in a workflow's constructor or in a `when().then()` callback.

The following code is reported by the rule:

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

createWorkflow("my-workflow", (input) => {
  try {
    return new WorkflowResponse(doSomething(input))
  } catch (e) {
    return new WorkflowResponse(null)
  }
})
```

Instead, use a step's compensation function or its error-handling options:

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

createWorkflow("my-workflow", (input) => {
  const result = doSomethingStep(input).config({
    continueOnPermanentFailure: true,
  })

  return new WorkflowResponse(result)
})
```

## Why it's Important

A workflow's constructor and `when().then()` callbacks run at definition time, not execution time. So, a `try/catch` there doesn't catch step errors. Use steps with compensation functions, `throwOnError: false`, or `skipOnPermanentFailure` / `continueOnPermanentFailure` instead.

Learn more in the [Error Handling in Workflows documentation](https://docs.medusajs.com/learn/fundamentals/workflows/errors).

## Fixable

This rule isn't auto-fixable.
