---------------------------------
Resolution: Fixed
> 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
> Assignee: Claus Ibsen
> Priority: Minor
> Fix For: 4.7.0
>
>
> 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 "KameletNotFoundException" is wrong anyways as the Kamelet has been part
> of the catalog in this case.
