'Deliver' failed. Preconditions have not been met: A work item must be associated with the change set.

Based on the question summary, you might think that, a work item was not associated with it. But thats not true, a work item was already associated with the change set. The really strange part is, all the pre-condition behaviour with respect to the "Deliver (Client) and (server)" are all removed, so that it does not claim to request for a work item to be attached with the delivery. Also, we tried in restarting the server though, but still the same issue persists. Would appreciate any help in fixing this strange issue.

Below is the snippet of the log from the build which it is actually failing with.
