H2OGeneralizedLinearEstimator () - Forecast error

I am trying to predict test time in Compag Kaggle using H2OGeneralizedLinearEstimator function. The model works fine on line 3 and the numbers are all reasonable. However, when I come to the prediction step, I get an error even though the test data frame matches the train data frame.

Has anyone seen this error before?

 h2o_glm = H2OGeneralizedLinearEstimator()

 h2o_glm.train(training_frame=train_h2o,y='y')

 h2o_glm_predictions = h2o_glm.predict(test_data=test_h2o).as_data_frame()

 test_pred = pd.read_csv('test.csv')[['ID']]
 test_pred['y'] = h2o_glm_predictions
 test_pred.to_csv('h2o_glm_predictions.csv',index=False)
