LangServer support LangGraph Command Update? / Human in the Loop

[EiinGeeeL]

Hello!
Do you know a way to send the command to the RemoteRunnable?

Im trying to update a PoC project to the new LangGraph update and I'm encountering this issue:

from langgraph.types import Command
from langserve import RemoteRunnable

cheese = RemoteRunnable("http://localhost:8000/cheese")

Define the input and stream

user_input = "Puedes resumirme los últimos 25 mensajes"
message_input = {"messages": [{"role": "human", "content": user_input}]}
for event in cheese.stream(message_input, config, stream_mode="updates"):
    print(event)
    print("\n")

The output:

{'cheeseagent': {'messages'....

{'__interrupt__': [{'value': {'question': '¿Estás seguro?', 'tool_call': {'name': 'MessagesVaultTool', 'args': ....

Trying to continue the interrupt:

for event in cheese.stream(Command(resume={"action": "continue"}), config, stream_mode="updates"):
    print(event)
    print("\n")

The error:

HTTPStatusError: Client error '422 Unprocessable Entity' for url 'http://localhost:8000/cheese/stream'
