trpc giving me a hooks error?

when a button is pressed im getting a hooks error, i think because im using this function as a consequence of the button press. What is the correct way to call this?

useMutation is a hook and can only be called in a function component as the error said. You need to do something like this

const YourComponent = () => {
  const mutation = trpc.user.updateUserInfo.useMutation()
  const saveChanges = async () => {
    mutation.mutate(whatevertheParamsYouHaveHere)
  }
}

const YourComponent = () => {
  const mutation = trpc.user.updateUserInfo.useMutation()
  const saveChanges = async () => {
    mutation.mutate(whatevertheParamsYouHaveHere)
  }
}
