First class results error using remote ray

I checked out https://github.com/PrefectHQ/prefect/pull/6908 branch on both local and remote machine, then ran this code (if address is omitted, it works). Any ideas @madkinsz?

from typing import List

from prefect import flow, get_run_logger, task
from prefect_ray.task_runners import RayTaskRunner
from prefect.settings import temporary_settings, PREFECT_LOCAL_STORAGE_PATH

# from prefect_dask.task_runners import DaskTaskRunner

@task
def say_hello(name: str) -> None:
    logger = get_run_logger()
    logger.info(f"hello {name}")

@task
def say_goodbye(name: str) -> None:
    # logs not currently working see https://github.com/PrefectHQ/prefect-ray/issues/25
    logger = get_run_logger()
    print("print goodbye")
    logger.info(f"goodbye {name}")

# run on an existing ray cluster
@flow(
    task_runner=RayTaskRunner(
        # 127.0.0.1:10001 is port-forwarded to the remote ray cluster
        address="ray://myaddress",
    )
)
def greetings(names: List[str]) -> None:
    for name in names:
        say_hello.submit(name)

if __name__ == "__main__":
    greetings(["arthur", "trillian", "ford", "marvin"])

Results in:
