"The destination execution context for this RPC was canceled while the call was still running." when using RPC

the RPC output (and input) is limited in 1MB to I have to use stream to bypass the limit
```rust
pub async fn my_function(data: String) -> Result {
let stream1 = str_to_readable_stream(String::from_utf8(out).unwrap().as_str());
let stream = wasm_streams::ReadableStream::from_raw(stream1);
Ok(ByteStream { inner: stream })
```

However I always getting "The destination execution context for this RPC was canceled while the call was still running." in caller service. Do you know what's the issue here
