> camel-aws2 producer health checks can throw NPE when AwsServiceException has
> no error details
> ---------------------------------------------------------------------------------------------
>
> Key: CAMEL-24251
> URL: https://issues.apache.org/jira/browse/CAMEL-24251
> Project: Camel
> Issue Type: Bug
> Components: camel-aws
> Reporter: Andrea Cosentino
> Assignee: Andrea Cosentino
> Priority: Major
> Fix For: 4.14.9, 4.18.4, 4.22.0

> h3. Problem
> Every AWS v2 producer health check catches {{AwsServiceException}} and
> records two details -- the HTTP status code and the AWS error code. The
> status code is guarded for null, but {{awsErrorDetails()}} is dereferenced
> directly:
> {code:java}
> } catch (AwsServiceException e) {
> builder.message(e.getMessage());
> builder.error(e);
> if (ObjectHelper.isNotEmpty(e.statusCode())) { // guarded
> builder.detail(SERVICE_STATUS_CODE, e.statusCode());
> }
> if (ObjectHelper.isNotEmpty(e.awsErrorDetails().errorCode())) { //
> e.awsErrorDetails() dereferenced unguarded
> builder.detail(SERVICE_ERROR_CODE, e.awsErrorDetails().errorCode());
> }
> builder.down();
> return;
> }
> {code}
> {{AwsServiceException.awsErrorDetails()}} is nullable (it is a plain builder
> field that defaults to null and is only populated when the SDK successfully
> unmarshals a structured error response). When an {{AwsServiceException}}
> reaches this block with {{awsErrorDetails() == null}} -- for example a 5xx
> whose body the SDK could not parse into an error, or an exception synthesized
> on an internal error path -- {{e.awsErrorDetails().errorCode()}} throws
> {{NullPointerException}}.
> The consequence is that the health check itself blows up with an NPE instead
> of reporting the endpoint as {{DOWN}} with the message it had already
> prepared: a genuine "service unreachable" signal is turned into a
> health-check framework error.
> The inconsistency is the tell: the author guarded {{statusCode()}} one line
> above but not {{awsErrorDetails()}}.
> h3. Scope
> The same copy-pasted block appears in 21 producer health checks: athena,
> comprehend, cw, ddb, ec2, ecs, eks, eventbridge, lambda, mq, polly,
> rekognition, step-functions, textract, timestream (query + write), translate,
> config, parameter-store, secrets-manager and security-hub.
> {{Textract2ProducerHealthCheck}} additionally dereferences
> {{e.awsErrorDetails().errorCode()}} in an {{equals(...)}} test that
> classifies certain errors as healthy, so it has two unguarded sites.
> h3. Proposed fix
> Guard {{awsErrorDetails()}} for null before dereferencing it, consistently
> with the neighbouring {{statusCode()}} guard.
> h3. Affected versions
> The block is present on {{main}}; the subset of these components that exists
> on {{camel-4.18.x}} and {{camel-4.14.x}} carries it verbatim (verified per
> module during backport).
> ----
> _Reported by Claude Code on behalf of acosentino, from an automated audit of
> the camel-aws components._
