[GEverding]

Hey,

I've been trying to run conductor in a test environment and I keep getting this error.

When I look inside of redis its creating keys but when I go to fetch work for a task I get the above error. I have a feeling its some sort of configuration error but I'm not sure. Have you seen this error before?

[v1r3n]

@GEverding I see there is a blank space in -Dworkflow.dynomite.cluster.hosts=dynomite-1:8102:us-east- 1c - for "us-east-1c".
Can you also add this property? -DEC2_AVAILABILTY_ZONE=us-east-1c

Are you running the docker images? The error is a bit strange, what are the steps to reproduce this error?

Adding @shailesh33 @ipapapa from Dynomite team.

[v1r3n]

@GEverding can you check the version of redis you are using? It should be 3.0.2 or greater.

[ipapapa]

@v1r3n hm, interesting error. To be safe Redis >3.0.7 is safe in production, but any above 2.8 would be fine. The Dyno still uses Jedis APIs 2.8.6.

@GEverding I am facing a similar issue is this issue got fixed.
If it is fixed for you, could you please let me know how to fix this issue
