Service binding type

What is the correct type for a service binding (worker to worker)? I have currently typed as

Fetcher

Fetcher

but I'm getting an error trying to provide a body to the request:

interface Platform {
  env: {
    API: Fetcher
  }
}

const formData = new FormData()

const res = await platform.env.API.fetch("/send-otp", {
  method: "POST",
  body: formData,
})

interface Platform {
  env: {
    API: Fetcher
  }
}

const formData = new FormData()

const res = await platform.env.API.fetch("/send-otp", {
  method: "POST",
  body: formData,
})

This gives me an error on

body

Type 'FormData' is not assignable to type 'BodyInit | null | undefined'

Type 'FormData' is not assignable to type 'BodyInit | null | undefined'

so I assume I'm typing the binding incorrectly as
