Federico Mariani created CAMEL-23984:
----------------------------------------
Summary: camel-yaml-dsl - unsupported top-level mapping YAML is
silently ignored: application starts with zero routes and no diagnostic
Key: CAMEL-23984
URL: https://issues.apache.org/jira/browse/CAMEL-23984
Project: Camel
Issue Type: Bug
Components: camel-yaml-dsl
Affects Versions: 4.21.0
Reporter: Federico Mariani
{{YamlRoutesBuilderLoader.preConfigureNode}}
({{YamlRoutesBuilderLoader.java:343-356}}) only special-cases mapping roots
that match {{kind: Pipe}}. Any other top-level *mapping* document falls through
as the raw node, reaches the non-sequence branch of {{configure()}}, matches no
{{instanceof}} in {{doConfigure}}, and the {{false}} return value is discarded
({{:162-164}}). The same silent drop exists in {{configuration()}} at line 327.
Failure scenarios:
* A user writes a route without the leading list dash ({{route:}} / {{from:}}
as a top-level mapping instead of a sequence item) — the application starts
cleanly with *zero routes* and no error or warning.
* A legacy {{kind: KameletBinding}} / {{kind: Integration}} file (support
removed in CAMEL-21695) — also silently ignored instead of a clear "no longer
supported" error.
Expected: the non-sequence branch should either attempt
{{ctx.mandatoryResolve}} (as the sequence branch does) or fail with an
"unsupported root node" error including the resource location.
