When calling scaling policies for a heat stack we get a code 500 response, but scaling is performed successfuly (nova instance is started and works).

<ErrorResponse><Error><Message>The request processing has failed due to an internal error:Timed out waiting for a reply to message ID 134e898cc179462f8839718ea35147d8</Message><Code>InternalFailure</Code><Type>Server</Type></Error>

There are no errors in heat-engine log, but I have found this in api-cfn.log

I had this same issue and for me it turned out that the message it wasn't getting was from ceilometer and the reason it wasn't getting it is because mongoDB filled up the disk. Once the mongoDB had space and ceilomter was restarted then it started working.
