-----------------------------------

             Summary: camel-robotframework - the consumer fails on every poll, 
and the producer fails on a null body or any null header or property
                 Key: CAMEL-26133
                 URL: https://issues.apache.org/jira/browse/CAMEL-26133
             Project: Camel
          Issue Type: Bug
            Reporter: Claus Ibsen
             Fix For: 4.24.0


Found while adding the catalog body types of mapstruct, robotframework, citrus 
and spring-event (CAMEL-24961, PR #28417).

h4. 1. The consumer can never deliver

The polled exchange of the consumer has a null body, and 
{{RobotFrameworkCamelUtils.createRobotVariablesFromCamelExchange}} (main 
2a465aa4814c, line 53) converts the body with 
{{mandatoryConvertTo(String.class, ...)}}, so every poll fails with 
NoTypeConversionAvailableException and the consumer never runs a test. Checked 
on 4.24.0-SNAPSHOT in-process.

Proposed: skip (or pass as empty) a null body when building the robot variables.

h4. 2. The producer fails on a null body or any null header or property value

The same {{mandatoryConvertTo}} is used for the body (main 2a465aa4814c, line 
53) and for every header and exchange property (line 91), so a producer call 
with a null body, or with any header or property whose value is null, fails. 
The doc's examples that use only headers or only properties fail for this 
reason. Checked on 4.24.0-SNAPSHOT in-process.

Proposed: skip null values (or map them to an empty value) when building the 
robot variables.
