> If timeline client fails more than the retry count, the original exception is not thrown.
Instead some runtime exception is raised saying "retries run out"
> # the failing exception should be rethrown, ideally via NetUtils.wrapException to include
URL of the failing endpoing
> # Otherwise, the raised RTE should (a) state that URL and (b) set the original fault
as the inner cause
