Geting TimeoutError despite using asnyc/await

[EmilioGarCan]

Question

I currently have a test endpoint set up which I use to call my application's API in order to create some sample data. This process uses asynchronous calls to retrieve the results from the API call, but despite this being the case, I'm still getting a timeout error.

This is the endpoint that calls the API:

@ui.page('/subpage')
    async def test_page() -> None:
        ui.label('Calling API to create sample data...').classes('text-xl')

        # Create goal
        goal = GoalInterface.DefaultSchema(
            UserId=1,
            Name='Snowflake Certification'
        )
        responseData = await hitApiPost('goals', data=goal.model_dump_json())
        ui.label(f'Created new goal: {str(responseData)}').classes('text-xl')

        # Create time block config (blueprint per day/every day)
        timeBlockConfig = TimeBlockConfigInterface.DefaultSchema(
            GoalId=1,
            DayOfWeek=0,
            Duration=3600
        )
        responseData = await hitApiPost('timeBlocks/configs', data=timeBlockConfig.model_dump_json())
        ui.label(f'Created new tb config: {str(responseData)}').classes('text-xl')

        # Create time block instance (trackable daily instance of tb config)
        timeBlockInstance = TimeBlockInstanceInterface.DefaultSchema(
            ConfigId=1,
            Date=datetime.now().date(),
            State=0
        )
        responseData = await hitApiPost('timeBlocks/instances', data=timeBlockInstance.model_dump_json())
        ui.label(f'Created new tb instance: {str(responseData)}').classes('text-xl')

        # Create time block event type (start, stop, resume, completion)
        timeBlockEventType = TimeBlockEventTypeInterface.DefaultSchema(
            Name='start'
        )
        responseData = await hitApiPost('timeBlocks/events/types', data=timeBlockEventType.model_dump_json())
        ui.label(f'Created new tb event type: {str(responseData)}').classes('text-xl')

This is the hitApiPost method being called:

async def hitApiPost(endpoint, data):
    async with aiohttp.ClientSession() as session:
        async with session.post(f"http://127.0.0.1:8000/{endpoint}", data=data, headers={"Content-Type": "application/json"}) as response:
            if response.status == 404:
                raise HTTPException(status_code=404, detail="Data was not found")
            if response.status != 200:
                raise HTTPException(status_code=response.status, detail=f"Error: {response.reason}")
            return await response.json()

What could I change to get rid of the timeout error? Appreciate any help

Who is raising the timeout? aiohttp or the browser viewing the /subpage?

[EmilioGarCan]

I'm getting a timeout error from the browser, I believe.

The post requests do finish executing despite the timeout, however.

Ok. Can you, please, try to create a minimum reproducible code example? Currently there are functions like model_dump_json, DefaultSchema etc which may cause this behaviour. Why is it important to provide a minimal reproducible example?

Fixed my issue by implementing asynchronous database interaction (PostgreSQL + asyncpg driver), this allowed me to bundle several calls together and significantly reduce execution time.
