ERROR: Service 'connect' failed to build: The command '/bin/sh -c confluent-hub install --no-prompt confluentinc/kafka-connect-datagen:latest' returned a non-zero code: 7

Currently trying to follow the Quick Start gude https://docs.confluent.io/5.1.4/quickstart/ce-docker-quickstart.html#ce-docker-quickstart

When trying to build the container I'm getting the following:

james.grant@DEM-C02XJGAAJG5H cp-all-in-one % docker-compose up -d --build

MacOS Catalina (10.15.7). corporate build (i.e. I don't have admin)
Docker Version 18.06.1-ce-mac73 (26764)

I've also tried % docker-compose build --no-cache connect as was suggested in a similar issue ticket but for an earlier release. Same result.

I also tried editing the Dockerfile and removed the --noprompt flag on step 3, and got the following output - it may be a "red herring" but there's an option that gets displayed neither option is selected:

The component can be installed in any of the following Confluent Platform installations:
  1. / (installed rpm/deb package)
  2. / (where this tool is installed)
Choose one of these to continue the installation (1-2): No line found

Any ideas?

Oh, and yes docker has been allocated 8GB of RAM
