Consul template fetching store key prefix errors using Nginx, Consul-template, and Docker

Question

New to Nginx and consul template, but I think I have everything working except I am getting lots of noise (100 or so error messages every 15-30 seconds) in the form of errors in the logs. Seems like it is consul-template errors that it can't connect/fetch the data...but it does fetch the data and build the templates correctly. So, not sure what the issue is.

How can I fix the errors? Or if they are to be expected, how can I not log them to stdout/stderr which is cluttering my nginx logging.

Thanks, Dan

Errors (getting these messages over and over again for various APPs):
