That SO deployment was strange. It has been done for a demo, and they said
they don't have a key manager at all. Hence the error. :)

Re: [Dev] Error in AM 2.0 gateway

[Supun Malinga]

Hi,

Actually I resolved the issue. It was due to throttle data war not been
deployed at the time server try to retrieve data. Fix was done by delaying
server starting time + depsync improvements (deleting apps from workers to
reduce startup time and avoid redeployment when depsync kick in).

Re: [Dev] Error in AM 2.0 gateway

[Harsha Kumara]

Hi Supun,

Did you setup the cluster with old throttling implementation? If it's with
new throttling implementation, please check your key manager
configuration.  Basically gateway try to fetch initial block conditions
details from the key manager.

Thanks,
Harsha
