tRPC subscriptions throw net::ERR_INCOMPLETE_CHUNKED_ENCODING 200 (OK) with httpSubscriptionLink

When using the Hono middleware as per the instructions, and setting up a tRPC subscription, the following error is thrown in console and a loop is created that eventually leads to a memory leak at the server: 
net::ERR_INCOMPLETE_CHUNKED_ENCODING 200 (OK)
net::ERR_INCOMPLETE_CHUNKED_ENCODING 200 (OK)
I don't see this with the equivalent Node http server. Is anyone else using tRPC subscriptions successfully with Hono? Repo here to reproduce: https://github.com/samuelgoldenbaum/honojs-middleware-issues-717

it doesn't seem to be that popular in Hono land. i imagine there are advantages over Hono RPC, but for many cases the latter does just fine i'm on the train rn so i can't pull + run your repro repo yet but i would probably start here: 
onCreate: publicProcedure.subscription(async function* (opts) {
    for await (const [data] of on(eventEmitter, EVENT.CREATE)) {
      const widget = data as Widget
      yield widget
    }
  })
onCreate: publicProcedure.subscription(async function* (opts) {
    for await (const [data] of on(eventEmitter, EVENT.CREATE)) {
      const widget = data as Widget
      yield widget
    }
  })
the error reads like the response is getting cut off, or is malformed have you tried adding a retryLink?
