Well, I was able to resolve my problem but only by going to the
application.conf file and setting it universally via
akka.http.host-connection-pool.client.idle-timeout. I suspect there was
another way, but the documentation on the many many variations of
idle-timeout make it difficult to figure out what needed to be changed.
The exception should probably be changed to specify which setting it came
from as a full path.
