Arch build not successful

[tennisparty]

I get the following error code when building for armv7hf (rpi3a+)
[Error] Error: The command '/bin/sh -c curl https://api.github.com/repos/balena-io/wifi-connect/releases/latest -s | grep -hoP 'browser_download_url": "\K.*armv7hf\.tar\.gz' | xargs -n1 curl -Ls | tar -xvz -C /usr/src/app/' returned a non-zero code: 2

I am using the following code blocks from the example

dockercompose.yml
wifi-connect: build: ./ restart: always network_mode: host privileged: true labels: io.balena.features.dbus: "1" io.balena.features.firmware: "1"

dockerfile.template
