TabPy. null error in prep flow about tabpy HOT 11 CLOSED

How large is the dataset you're passing?

I'd also suggest filing a support ticket with Tableau.

from tabpy.

not sure how to tell but in theory fairly large 100K rows

I'd also suggest filing a support ticket with Tableau.

filing a ticket with tableau support is like talking to a brick wall - want to make sure I'm not missing anything first as that route is a long road.

The first thing I'd try is setting the timeout parameter much higher in TabPy, it may be timing out.

Is Prep crashing or just hanging?

I did that - pushed it to 30min but still hangs and doesn’t time out after the 30min which makes me think this isn’t it

Is Prep crashing or just hanging?

Just hung with the error - I can still do things in prep it’s just not getting a good response from tabpy

Can you try filtering the dataset to something small like 5k rows and see if that works?

good idea - I tried 5K, 500, and 5 - all resulted in the same error

System error: Unknown Error when setting up request to TabPy. null

yet I have no issue when calling the same function tabpy calls outside of prep

from tabpy.

Can you confirm even a basic call to TabPy works from your Prep setup, like running a function to add 2 columns together?

yes as I have another script in the same flow that works fine.

from tabpy.

This seems like there may be an error running with this code specifically then, which is hard to comment on.
