Hi team..
Im facing an issue, im hoping i can get some help on.. Most probably something i have done to break things..

so..
I have an interrupted thread.. Waiting on human confirmation
TraceID: 1f05e9d4-136a-6daa-97a4-89a4622938c1
RunID: 5bce9361-7b42-4cd6-87de-814e3150133d

its stopped on should continue and the state has a user and transactions.
and my state wrapper is

class State(MessagesState):
    transactions: dict[str, list[dict]]
    statement_filter: dict
    user: dict

however on my typescript client when i do

    console.log("thread")
    console.log(await this.client.runs.get(threadId, runId));
    let finalResult = await this.client.threads.getState(threadId);
    console.log("finalResult");
    console.log(finalResult);

    console.log('transactions');
    // @ts-ignore
    let finalResultElementElement = finalResult['values']['transactions'];
    console.log(finalResultElementElement);

i get

while i can see user and messages, transactions are missing
If it helps at all.. Things used to work until i changed this transaction processing to a sub-agent
but im using a shared state object between the parent and sub agents
The parent populates the user which seems to be present, the sub agent adds the transactions which seem to be missing when resuming an interrupted thread

Oh also im using the webhook method get notified when the execution gets interrupted..

okey after some research i discovered checkpointing
