------------------------------------------
Summary: Misleading error message when Kamelet misses mandatory
field value
Key: CAMEL-20892
URL: https://issues.apache.org/jira/browse/CAMEL-20892
Project: Camel
Issue Type: Improvement
Components: camel-kamelet
Affects Versions: 4.6.0
Reporter: Christoph Deppisch
When a Camel route uses a Kamelet but misses a mandatory field for some reason
the error message is quite misleading. The error reports a
"KameletNotFoundException" in the StackTrace which is misleading because the
real error is an "IllegalArgumentException" due to the missing mandatory field.

The user needs to find the right part of the StackTrace to find out what is
going on: "Route template set-body-action the following mandatory parameters
must be provided: value"
The "KameletNotFoundException" is wrong anyways as the Kamelet has been part of
the catalog in this case.
