HubSpot search API — RuntimeError: cannot join current thread

[NickNaskida]

Hello, I am using this package in my FastAPI application:

async def handle_email_payload(email, db_session):
    public_object_search_request = PublicObjectSearchRequest(
        filter_groups=[
            {
                "filters": [
                    {
                        "value": email,
                        "propertyName": "email",
                        "operator": "EQ"
                    }
                ]
            }
        ],
        properties=["phone", "instagram_handle"],
        limit=10
    )

    try:
        thread = hubspot_client.crm.contacts.search_api.do_search(
            public_object_search_request=public_object_search_request,
            async_req=True,
        )
        result = thread.get()
        fetched_contact = result.to_dict().get("results")[0]
    except ApiException as e:
        logger.error(f"Failed to fetch contact with email: {email}. Error: {e}")
        return
    except Exception as e:
        logger.error(f"Failed to fetch contact with email: {email}. Fetched contact: {result.to_dict()}. Error: {e}")
        return

    contact_id = fetched_contact.get("id")

This code raises this error every time:

Exception ignored in: <function ApiClient.del at 0x15a61fc40>
Traceback (most recent call last):

Any suggestions on how to resolve this issue?
