[imprakharshukla]

📜 Description

novu.serve when used with next 15.5, throws errors when being built.

  // Export named HTTP methods
   export const GET = serve({ workflows })
  export const POST = serve({ workflows })
  export const OPTIONS = serve({ workflows })

It didn't happen with the previous i.e. 15.4.x versions.

Errors:

        Types of parameters 'event' and 'event' are incompatible.

      ```

### 👟 Reproduction steps

1. Upgrade to next 15.5.
2. have a route serving novu workflows like this:
```ts
import { serve } from '@novu/framework/next'
import {
  jobUpdateRejected,
} from '@yobr/trpc/novu/workflows'

// Collect all workflows
const workflows = [
  jobUpdateRejected,
]

// // Export named HTTP methods
export const GET = serve({ workflows })
export const POST = serve({ workflows })
export const OPTIONS = serve({ workflows })

👍 Expected behavior

It should build successfully, commenting the .serve function makes it build.
