Building a Custom Activity, here I am using sfmc-fuelsdk-node npm package.
SFMC account is a Enterprise account, I am are trying to retrieve all DE including Child BU and getting a error as "MemberID XXXXXXXX does not have access to ClientID XXXXXXXX".
MemberID - Parent BU ClientID - Child BU
When I use Parent BU ID as ClientID, I am able to retrieve DE, but not those that are under childBU. To retreive ChildBU DE's, used ClientId as ChildID with Parent BU AccessToken.
Can someone suggest me a solution related to this error [node].
