I am running into error while langgraph is running : TypeError: langgraph.pregel.write.ChannelWrite.do_write() argument after ** must be a mapping, not str

[nishkaloc]

I am using crewai along with langgraph, I use stategraph to create conditional nodes , below is my code

from typing import TypedDict, Any
class AgentState(TypedDict):
action: dict

def condition_check(flag):
print(flag)
if "internet" in flag["action"].lower():
k = "InternetAgent"
elif "pubmed" in flag["action"].lower():
k = "PubMedAgent"
elif "rag" in flag["action"].lower():
k = "RagSystem"
else:
k = "None"
print(k)
return k

def check_route(flag,user_query):
a = [RouterAgent]
task = [router_task(flag,user_query)]
r = Crew(agents=a,tasks=task,verbose=False)
k = r.kickoff()
return {"action": k}
def internet_node(user_query):
pipeline=[internet_task(user_query),summary_task()]
a=[InternetAgent,SummaryWriterAgent]
int_crew=Crew(agents=a,tasks=pipeline,verbose=True)
return int_crew.kickoff()

def pubmed_node(user_query):
pipeline=[pubmed_task(user_query),summary_task()]
a=[PubMedAgent,SummaryWriterAgent]
pub_crew=Crew(agents=a,tasks=pipeline,verbose=True)
return pub_crew.kickoff()

def all_node(flag,user_query):
pipeline=[router_task(user_query),internet_task(user_query),pubmed_task(user_query),summary_task()]
a=[RouterAgent,InternetAgent,PubMedAgent,SummaryWriterAgent]
all_crew=Crew(agents=a,tasks=pipeline,verbose=True)
return all_crew.kickoff()

from langgraph.graph import StateGraph,END

class Workflow():
def init(self,flag,user_query):

workflow = StateGraph(AgentState)
self.flag = flag
self.user_query = user_query

workflow.add_node("check_route", lambda flag=flag,query=user_query: check_route(flag,query))
workflow.add_node("internet_search", lambda query=user_query: internet_node(query))
workflow.add_node("pubmed_search", lambda query=user_query: pubmed_node(query))
workflow.add_node("all_search", lambda flag=flag, query=user_query: all_node(flag, query))



workflow.set_entry_point("check_route")
workflow.add_conditional_edges(
    "check_route",
    condition_check,
    {
        "InternetAgent": 'internet_search',
        "PubMedAgent": 'pubmed_search',
        "None": 'all_search'
    }
)
# Add edges from each search node to END node
workflow.add_edge("internet_search", END)
workflow.add_edge("pubmed_search", END)
workflow.add_edge("all_search", END)

self.app = workflow.compile()

flag="Internet"
user_query = "who is virat kohli's son?"
workflow = Workflow(flag,user_query)
app = workflow.app
app.invoke({})

I receive this output
