Hi @alfarzan,
I got a weird error, Could you please look into submission #116916 please?
Yes that is a weird one 
, it looks like the submission succeeded based on the error but it “failed” anyway. Can you resubmit? I resubmitted your zip successfully (after setting your prices to zero).
This is the submission.
Also @marco_de_virgilis I noticed that your fit_model function is empty. This is not allowed and your model may be disqualified in the future if the fitting function is not included.
We allow the submission of a trained model to speed up the submission process but in principle we may retrain your models and if the model doesn’t exist then it causes an issue on our end
