Hi Souma
ususally we follow the steps.
1. We check the script in Vugen so all the required operations such as CRUD/Search by script.
2. We runt the scripts in Controllor/ALM as some times script fails due to additonal components.
3. If your current scrit is working then cross verify with the developer how is the additional component is affected to the application, as Djay has suggested talk to the Developer.
Thanks
Asif
