Why my scoring recipe failed after updating my test dataset?

[Mattsco]

Got this error message when executing my scoring recipe:

[15:04:50] [INFO] [dku.utils] - Exception: An error occurred during dataset write (mMZScq4XA9): RuntimeException: Schema incompatibility: 38 columns in data, 37 columns in target dataset.

It seems that the schema of your input dataset changed. You can get DSS to detect the schema incompatibility and offer to automatically update the output dataset's schema simply by re-saving your scoring recipe.

In Flow, double-click the scoring recipe, then click Save, you should see this box:

Click Update schema to override the output dataset's schema. You should now be able to run your scoring recipe.
