Check this issue on a newly created instance with specified OAR. Single region, New user and estate >> All objects owned by this user

• No problems found accessing the five instances of the 'land radio' object. Dialog shown all times

Retried with new region assigned to the Real Estate Owner >> all objects owned by Real Estate Owner

• No problems found accessing all radio instances

Verified operational in both Grid and Standalone mode - No problems found.

Looking at the error code from the log you posted, that's a call to the UserService, nothing to do with the DotNet engine.

i'll improve the DotNet Engine a little bit. but first i need to reintegrate the bulletsim again. The error means, that the Process can not lookup the username. i think its an old styled code here.

This bug actually means that user cannot be found in the database itself (land radio: Error executing script: System.NullReferenceException: Object reference not set to an instance of an object).

the object in this error is the user's name which it couldn't find in the database itself, thus it throws this error. Some IARS unfortunately this may or may not be a problem. However I have tested the IAR locally both in Standalone and Grid Mode and this appears to be working correctly.

It is very much likely this is a non code bug and just an issue with the database. Therefore this is why the error came up and is not related to DNE itself.

Closing this as not further reports have been received. Testing using the specified Oar & script on a new instance did not show any errors.
