When creating a new REPO project, leaving the platform field blank should result in no -p flag being passed to the repo init command. However, the following command is generated, resulting in a failure:
repo init -u ssh://xxx/yyy -b master -p --depth=1 --current-branch
An empty -p is generated, causing --depth=1 to be interpreted as the platform value.

Manually specifying the value 'auto' will work as a work-around, but this is NOT the expected behavior.

This is a new regression issue, as this used to work as expected.
