Mutations seem to be broken

[b93rn]

I tried running the batch example and the mutation example.
In both examples predicates are created, but the counts in the data explorer are all 0, except for the Username in the mutation example, which is created by an upsert.

In the batch example i got no errors. For the mutation example i got the following error:

Result: IsSuccess='False', Reasons='Error with Message='No transaction set''
