Error using last version of mac

I got this error, using the last version
##[error]Cannot read property 'substring' of undefined

@Geertvdc @mislav How is this expected to work?

action.yaml defines hub-version but the code in setup-hub.ts is checking for version.

If version is specified there is a warning Unexpected input 'version', valid inputs are ['hub-version']. If not it fails with Cannot read property 'substring' of undefined?
