Datomic version 0.9.5153 is quite old at this point (it was released in early 2015), and used AWS SDK version 1.8.11, so I suspect you're hitting a dependency version mismatch there.

There have been several critical updates to Datomic since that release, so I'd encourage you to move to the latest release (0.9.5561.62) if at all possible.
