How to disable route timeout in Envoy? - networking

Question

I'm trying to use http2/grpc streaming, but my connection cuts off in 15 seconds. The documentation on the timeout setting says to set the timeout to 0. However when I do this then Envoy throws an error on startup complaining that 0 isn't a valid value for the Duration type.
How do I disable the route timeout?
Here is my Envoy config .yml

access_log_path: "/dev/null"

You almost got it. The only change you need to make is to go from an integer to a duration. So rather than "0", you need to specify "0s" for zero seconds.
I verified this by setting timeout: 0s in your config.yaml and everything started up.
