Hey all, I am try to return HTTPexception from my nodes in kedro, exception is imported from FastApi. But i recieve this error

DatasetError: Failed while saving data to data set MemoryDataset().
HTTPException.__init__() missing 1 required positional argument: 'status_code'

This is the code From FastApi import HTTPException

if df.shape[0]==0:
            return HTTPException(detail='Sufficient Data not available',status_code=404)

Do I have to create a custom data set?

I’m not so sure this is a Kedro issue, but IO is normally done via datasets yes

Seems a lot of work, i should return a string instead and let the outer function outside kedro scope handle it

I guess the question I have

I am trying to run the kedro pipeline on an existing FastAPI code. I am using kedrosession to do that. So if during pipeline data does not exist I need to show the error in fast api response

there are some other examples of people doing this https://bitbucket.org/indiciumtech/kedro_fast_api/src/master/ https://medium.com/indiciumtech/how-to-build-models-as-products-using-mlops-part-4-deploying-models-in-apis-with-kedro-fast-api-15f13e67c080 https://github.com/Galileo-Galilei/kedro-serving/blob/main/kedro_serving/running_server.py
