> Using the Datasonnet Header to specify the media type for the body doesn't
> work because then doEvalute() inte DatasonnetExpression fails to detect the
> media type the body is set like this:
> {code:java}
> body = new
> DefaultDocument<>(MessageHelper.extractBodyAsString(exchange.getMessage()),
> bodyMT);{code}
> This only works if the current body is a String.
> If I remove the bodyMediaType attribute from the datasonnet processor in the
> route in the test case testReadJava(), which has a java object as body and a
> header that looks like this:
> {code:java}
> /** DataSonnet
> version=2.0
> input payload application/x-java-object; DateFormat=yyyy-MM-dd
> */
> {code}
> Then this test case fails with:
> java.lang.IllegalArgumentException: Problem executing script: sjsonnet.Error:
> attempted to index a string with string name at line 24 column 24 of the
> transformation
