---------------------------------------
Summary: Datasonnet header can't be used to set bodyMediaType
Key: CAMEL-17067
URL: https://issues.apache.org/jira/browse/CAMEL-17067
Project: Camel
Issue Type: Bug
Affects Versions: 3.11.0, 3.11.2, 3.11.1
Reporter: Henrik Karlsson
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
