Re: Unable to delete Valuestream from Composer which was created via script
I have not seen this specific error with the root cause being a "null". This would seem to imply that the entity does not actually exist and that we may dealing with a Ghost Entity here. If possible I would recommend restarting ThingWorx to see if the Value Stream is no longer present. Should this be the case I would recommend having a look at CS198580 which explains the concept of Ghost Entities in more detail.
