Fastify instrumentation may not report errors?

[unflxw]

We saw an issue during a call where a customer (Intercom link) did not see errors reported from their Fastify application's error handlers automatically. (This customer was affected by #974, but the issue persisted after the workaround was applied)

Another workaround was used, in which a custom Fastify error handler was used to manually forward errors to AppSignal.

To do

• [ ] Attempt to reproduce in our test setup?
• If reproduced:
  • [ ] Document custom error handler
  • [ ] Report to upstream OpenTelemetry instrumentation

:heavy_check_mark: All good!

Would you be able to provide the solution for the custom fastify error handler? I'm experience the same issue and would like to try the given solution.

This is fixed in newer versions of @appsignal/nodejs (^3.4.8).
