The command '/bin/sh -c apk add --no-cache git' returned a non-zero code: 4294967295

I am new to Docker and following the tutorial for Developers at https://hub.docker.com/?overlay=onboarding&step=build

Everything is OK until I get to the point where I enter the command: docker build -t darrenwnpi/cheers2019 .

I actually enter docker build --build-arg HTTP_PROXY=http://myproxy:4980 -t darrenwnpi/cheers2019 . where myproxy is the address of our inhouse proxy.

I get the following response back.

I am running on Windows 10 Pro Version 2004 (OS Build 19041.572). As a bit of background to get round other problems I have already set the proxy in the HTTP section of Docker Desktop > Settings and set experimental to true in the daemon.json.
