Bug where 2 requests are fired at once. TRPC batches them. Can I cancel the 2nd via ProcedureOption?

Hey all. I have a bug where my app fires two identical requests at the same time. This happens do to some weird upstream auth listener logic. Ideally TRPC can help me mitigate this. I want to configure ProcedureOption such that it doesn't batch, but rather only lets the first request to go through. Is this possible?

const updatedCartItems = await trpcClient.user.cart.replaceCartOnAuthLoaded.mutate(
  {
    anonymousCartItems,
  },
  {
    onlyOneAtATime: true,
  },
)

const updatedCartItems = await trpcClient.user.cart.replaceCartOnAuthLoaded.mutate(
  {
    anonymousCartItems,
  },
  {
    onlyOneAtATime: true,
  },
)

React-Query should do de-duping for you no? Do you have any more details or a reproduction of the issue? If it's batching up 2 requests, one of which RQ would be cancelling, this may be a bug on our side?

No - they're both running
