Same issue here wih v2.5.2 - some review requests can be updated, not others.
For the error to be "Review request with this Commit ID and Repository already exists."
sounds like it's either incorrectly attempting an insert of a new review request with the same information,
or making an update that's breaking the constraints of the table(s)
