Question / Problem:
There is a Kapow robot from KTA which using some Querydatabase actions.
The robot is working fine when i run it from Design studio and Management console.
It is working fine even from KTA when i use REST option during kapow integration in KTA, but througing Database error when i use the .NET option.
Answer / Solution:
There is no mapping concept for the API.
Therefore, API does not know of the mappings in Design Studio or Management Console and can not use them.
Workaround is as you mentioned to use the same name for the mapping and the schema.
The database mapping name in the robot, must be changed to match the db as it is registered on the cluster.
