Field Validation on INSERT error installing git-source-control

Hi - I'm refreshing my IRIS instance, now upgraded to 2025.1, and ensuring IPM is installed in each namespace, as well as git-source-control, but in my first attempt I get this error. 

Everything else seems to work - but why the error (I'd like to get rid of it) ?

zpm:AULIBRARY>install git-source-control
