Cause

The Groovy Script must be placed at:

<install_dir>/obt/extensions/runtime/masking

At Designer, when add the groovy use the filename without extension.

Fix

Create a Groovy script that includes the following signature:
Object mask(Object param);
Copy the Groovy script into the folder:
<install_dir>/obt/extensions/runtime/masking
In Designer, click the Data Masking tab in the cartridge and then click Custom Masks.

Custom

4. Click Add and type the filename (case-sensitive) without any extension (.grovvy) of your Groovy script in the Custom Data Masking dialog, then click OK.

5. Then add the custom script to the columns:
