I've just started to get my head round SSJS and tried this simple script from a tutorial as the script I wrote (same logic) was erroring in the same way.
I am looking to upsert data into a DE from a JSON file but keep getting this error:
Error Message: "Unable to retrieve security descriptor for this frame." Description: "System.InvalidOperationException: Unable to retrieve security descriptor for this frame. - from mscorlib "
is this due to permissions, the source of the data or do I need to include some sort of authentication token when trying to enter data into the DE? any help would be greatly appreciated.
DE: non sendable, all fields match what's in the script including the primary keys, rest of fields are nullable.
