I am trying to implement a Hono sender that sends a large amount of data to a Hono instance however I keep running into an issue with the sender running out of credits. Specifically. "cannot send message while waiting for replenishment with credit". How can I trigger the sender to be replenished with credits or wait for more credits to be available before sending the next message?
One reason for this may the fact that you do not have a consumer running when sending telemetry data. Hono does handle back-pressure by waiting for a consumer to be capable of receiving messages. However, if there is no consumer currently running, then then your sender will not receive credits as well.
