New AutoML error: Object 'dummy' not found for argument: model_id

Question

When running H20's AutoML function I suddenly get this error, which I couldn't find anywhere else on the internet:

ERROR MESSAGE:

Object 'dummy' not found for argument: model_id

I ran the same code before without problems, the error only occurred after I added features to my dataset (all features are numeric, data is confidential so can't post a working example).

aml <- h2o.automl(x = features, 
                  y = response,
                  training_frame = train_hf,
                  validation_frame = valid_hf,
                  balance_classes = TRUE,
                  max_runtime_secs = 60) # tried 3600 as well

Has anybody encountered this error before and resolved it?

Hi Shirin, are you able to replicate this problem on a public numeric dataset? e.g. https://s3.amazonaws.com/erin-data/higgs/higgs_train_10k.csv Can you also post the code that you used to add features (assuming you added the columns in R)? Also can you try again on the latest stable: http://h2o-release.s3.amazonaws.com/h2o/latest_stable.html and also the latest nightly: http://h2o-release.s3.amazonaws.com/h2o/master/latest.html to see if the problem occurs there too? Thanks! — Erin LeDell, Feb 26 '19 at 23:47
The code to add features comes from preprocessing and unfortunately can't be shared due to privacy concerns of the customer. But the structure of these features is not different to the previous version. — Shirin Elsinghorst, Mar 21 '19 at 13:06

This problem can be solved by specifiying what particular algos to use. You can check this: https://docs.h2o.ai/h2o/latest-stable/h2o-docs/data-science/algo-params/include_algos.html

This error is reproducible by using: include_algos=c("StackedEnsemble"), only.
