trpc 11 superjson transformer not working with unstable_httpBatchStreamLink

Hello! I have been using

httpBatchLink

httpBatchLink

for quite a while but wanted to swap to

unstable_httpBatchStreamLink

unstable_httpBatchStreamLink

. However, I noticed that any procedure returning a

Map

Map

isn't being converted correctly. It is only an issue when using

unstable_httpBatchStreamLink

unstable_httpBatchStreamLink

. Is this a known issue?
