----------------------------------------
Summary: camel-huaweicloud-functiongraph: include the region in
the invoke URN when endpoint is set, and read the response body robustly
Key: CAMEL-24765
URL: https://issues.apache.org/jira/browse/CAMEL-24765
Project: Camel
Issue Type: Bug
Reporter: Andrea Cosentino
Assignee: Andrea Cosentino
Two functional issues in camel-huaweicloud-functiongraph, found by a gap audit
(verified against main):
* The ClientConfigurations constructor sets EITHER endpoint OR region (if
endpoint is set, region is never copied, even when the user also set region).
composeUrn then formats urn:fss:%s:... with a null region, producing
urn:fss:null:<projectId>:function:... which FunctionGraph rejects. Any route
configured with the endpoint URI param invokes with a malformed URN. Fix:
populate region independently of the endpoint/region client-init choice so the
URN always carries the region when it was supplied.
* FunctionGraphUtils.extractJsonFieldAsString reads the response body via
gson.fromJson(json, JsonObject.class).getAsJsonObject("body").toString(), which
throws ClassCastException when body is a JSON string/primitive (the normal
shape for HTTP-triggered functions) and NPE when body is absent. Fix: fetch the
element with get(), null-check it, and stringify it directly.
Also fixes the proxy guard that used ObjectHelper.isNotEmpty(getProxyPort()) on
a primitive int (always true) so a proxyHost with no proxyPort configured a
proxy on port 0.
