Unable to updateSate of non messages property

[darthShana]

Hi Team..

My aim is to process a list transactions and finally save them..
"processing" will include filtering them, classifying them and updating the classification through user input

I put in interrupt before the ask_human tool call to get the user to confirm or to update things
To be explicit i put the transactions as a separate field in State

class State(TypedDict):
    messages: Annotated[list[AnyMessage], add_messages]
    transactions: dict[str, list[dict]]
    statement_filter: dict

when the user updates a transactions
in my client i do

const state = await this.client.threads.getState(this.thread['thread_id']);
// @ts-ignore
const toolCallId = state['values']["messages"][-1]['tool_calls'][0]['id'];

const toolMessage = [{"tool_call_id": toolCallId, "type": "tool", "content": {"foo": "goo"}}];
await this.client.threads.updateState(
  this.thread["thread_id"],
  {
    values: {
      "messages": toolMessage
    },
    asNode: 'ask_human'
  }
)
const streamResponse = this.client.runs.stream(
  this.thread["thread_id"],
  this.assistantId,
  {
    input: null,
    streamMode: "messages",
  }
);

however invoking the graph errors just before ask_human

Any assistance would be appreciated....

turns out this is caused by nodes not being correctly connected
