6-6:categoriesis empty – confirm this is intentional.If the build pipeline expects at least one category (e.g.,
observability,performance,devops) an empty array could break filtering or navigation pages.

🛠️ Refactor suggestion
Ensure the span is always ended – use finally.
If an unhandled error is re-thrown before span.end() executes, the trace will be left open, skewing duration metrics and blocking some back-ends from flushing the trace.
- const span = tracer.startSpan('handleRequest');
- try {
- // Business logic here
- span.end();
- } catch (error) {
- span.setTag('error', true);
- span.log({ event: 'error', message: error.message });
- span.end();
- throw error;
- }
+ const span = tracer.startSpan('handleRequest');
+ try {
+ // Business logic here
+ } catch (error) {
+ span.setTag('error', true);
+ span.log({ event: 'error', message: error.message });
+ throw error;
+ } finally {
+ span.end();

In apps/www/content/glossary/distributed-tracing.mdx around lines 66 to 81, the
span is ended inside both the try and catch blocks, but if an error is thrown
and re-thrown, span.end() might not execute properly. Refactor the code to move
span.end() into a finally block to guarantee the span is always ended regardless
of success or error, ensuring proper trace closure.
This PR adds or updates the Distributed Tracing.mdx file in the API documentation.
