What's happening is that the user account being used to run the RESTful command is not consistent across all landscapes in the DSS.

Resolution

If on Spectrum 21.2.10, either upgrade to 21.2.12 or later releases where this fix is incorporated or ensure that the following two patches required to fix this issue on 21.2.10 are installed: 

For the OneClick server -

21.02.10.PTF_21.2.1008a

and on the SpectroSERVER:

Spectrum_21.02.10.D72 

Also, sync across all users from the MLS to the other SpectroSERVERs in a DSS environment. On the MLS, under:

OneClick -> Users tab -> User -> Component Detail

click on the Synchronize Now button:

This will sync the users across all landscapes and update their user models to make them consistent regardless of which landscape the OneClick server is communicating with.
