Fixes this error ["ERROR: invalid tag \"aqa_u2404.ARM32\": repository name must be lowercase"]

Is the | upper necessary when we've fixed the arm32_suffix to be lower case?
If not, I'd be tempted to leave it out in order to avoid any potential confusion with "masking" incorrect values in the automation.

The arm32 suffix needs to be lowercase in the build image tag only, so only during the docker build command. I've used the | upper convention when naming the container in the docker run command as I dont think docker cares about upper/lower case when naming the actual running container, just the image tag

Makes sense - thanks.
