Claus Ibsen commented on CAMEL-16906:
-------------------------------------
This causes test failures in other components such as camel-serlvet and
whatnot. But the general problem is that fallback type converter should be used
with extra care.
> Platform-http components fail when using unmarshal

> Key: CAMEL-16906
> URL: https://issues.apache.org/jira/browse/CAMEL-16906
> Project: Camel
> Issue Type: Bug
> Components: camel-platform-http-vertx
> Affects Versions: 3.11.1, 3.12.0
> Reporter: Pasquale Congiusti
> Assignee: Pasquale Congiusti
> Priority: Major
> Fix For: 3.13.0
>
>
> When we run a route which is using platform-http component and we try to
> unmarshal to json (and I suspect also any other dataformat), there is a
> failure due to a missing conversion type.
> For example:
> {code}
> from("platform-http:/hello?httpMethodRestrict=GET").
> setBody(simple("{\"hello\": \"world\"}"))
> .unmarshal().json();
> {code}
> Will fail because there is a [mandatory conversion from Map to
> ByteBuffer|https://github.com/apache/camel/blob/main/components/camel-platform-http-vertx/src/main/java/org/apache/camel/component/platform/http/vertx/VertxPlatformHttpSupport.java#L183]
> that is failing.
