I am getting an exception that I pasted below. It describes a transaction
error, but I have not programmed any transactions. On top of that, the
request that I made should not have changed any data. Has anyone else been
getting errors like this?
Caused by: java.lang.IllegalArgumentException: can't operate on multiple
entity groups in a single transaction.
