In the unlikely scenario that
LocalExporter::resolveBulk
throws an exception, then we should mark thelistener
as having failed.As discussed with @martijnvg, this is a follow-up to #35765, which already ensured that this call was async, but did not catch the [unlikely] exception.
A future PR should cleanup the
LocalExporter
to make it a bit cleaner to test (more unit tests and less integration tests taking 20s+) as well remove the dependence on receiving cluster state changes to initialize the exporter.Closes #35797
