Error when running XGBoost Linear Ensemble Learner (Regression)

[whois_rb]

Hi all,

Tried running a regression with the XGBoost Linear Ensemble Learner and encountered a strange error.

In the node settings, had selected CoordDescent and Thrifty using the Booster drop-downs:

However, got an error which appears to indicate that there’s a typo somewhere in the code of the node (i.e. error references “trhifty” even though selection was for “Thrifty”):

Hoping someone can shed some light on this, and/or let me know how to get this to run successfully.

Here’s the workflow:

Thanks!
