@stevenwinship I'm getting an error in the DataRetrieverApiIT. On line 103 it's finding 0 instead of 1. Also the branch is out of date with dev.

[stevenwinship]

I'm not seeing the error. There is a 4 second sleep that might be too short?
I can't imagine that 4 seconds would be too short though

I updated the branch and will run it again

Thanks for the update
