Hi All,

Im making use of Database cleaner API and action ModuleVersion_ListOldest to list the oldest espace versions.

There are no input params for credentials to the API.

But Im getting below error when I use this API action 

user id: 0, username:  attempted to obtain a list of module versions without having the necessary credentials..

Can anyone help me out

Hello,

From here: https://success.outsystems.com/Documentation/11/Reference/OutSystems_APIs/DbCleaner_API

Your application (module using the api) must use Service Center as User Provider and the user must be an IT user with Change & Deploy access privilege to the environment.

Cheers
