Hi Slact, thank you for making nchan it is sweet. I have encountered an error where the nchan_message_id variable and prev_message_id variable are not being forwarded to my upstream when using nchan_publisher_upstream_request. you can see from the logs that in the url and the headers of the requests the values are not there. would you know how to fix this? is it because I do not have redis pass in all of my publisher configurations only in my subscriber ?
I am using alpine linux , with version v1.3.6 see below for my configuration.
