I had a quick look at the code and I feel that validation info (which is used to take throttling decisions) may not be available at the time this error occurred, where the reason can be, throttling rules were not executed for this tenant (of course this is a bug). May be you created a tenant, deployed the service and restarted the server, but there was no chance for throttling rules to run during that time period (it runs periodically). Ohh... throttling rules are run only in Manager, so without manager running, there may be no throttling validation info. If above is the correct explanation, we have to gracefully handle it. I hope Manager was not running at this moment?
