async inside link next handler possible ?

Hey everyone, Today I had to do a bit of refactor, and I'm wondering something. I had to turn a synchronous function into an asynchronous one, and ended up needing async into the trpc "link" like so: 
// From
const link: TRPCLink<CLIRouterType> = () => {
  return ({ prev, next, op }) => {
    next(op, (result) => {
      if (is401Error(result)) {
          synchronousFunction(result)
      }
      prev(result)
    })
  }
}

// to
const link: TRPCLink<CLIRouterType> = () => {
  return ({ prev, next, op }) => {
    next(op, async (result) => {
      if (is401Error(result)) {
          await asynchronousFunction(result)
      }
      prev(result)
    })
  }
}
// From
const link: TRPCLink<CLIRouterType> = () => {
  return ({ prev, next, op }) => {
    next(op, (result) => {
      if (is401Error(result)) {
          synchronousFunction(result)
      }
      prev(result)
    })
  }
}

// to
const link: TRPCLink<CLIRouterType> = () => {
  return ({ prev, next, op }) => {
    next(op, async (result) => {
      if (is401Error(result)) {
          await asynchronousFunction(result)
      }
      prev(result)
    })
  }
}
Is that okay to do so? Turn the callback of next into an async ?
