"error reverse proxying request"

[Peter Bull]

I am looking for some help.

My eventing function is running, no errors in the function log,  and every time it runs, 10 minutes in I get an error (shown below) and then the function is called a second time, the error quickly repeats and the function is called again, until there are multiple (over 6) incantations running.

The function is configured with a container concurrency of 1, autoscaling settings of min-scale=0, max scale=1  and a metric=concurrency.

Anyone got any ideas how to fix this?
