I failed to tune my XGBoost regression model. And I'm having problems locating the error because the error messages were truncated like this:

```
❯ Generating a set of 3 initial parameter results

x Fold1: preprocessor 1/1, model 2/3: Error in xgboost::xgb.DMatrix(x, label = y,...

x Fold2: preprocessor 1/1, model 3/3: Error in xgboost::xgb.DMatrix(x, label = y,...

```

How can I get the complete messages? Thanks.
