Hi @carsten_1879,
Thanks for trying it out. It is new, and has not been tested as much against older repositories. That said, we've reproduced this error and it's now fixed in the latest build - buildmaster:25.0.0-ci.28
if you would like to try it again. It's caused by older repos that don't support offset deltas being transmitted during a clone or fetch. Small repos that we used for testing ADOS so far were not large enough to have deltas at all, so those worked. So far as I can tell, the repository name containing a dot doesn't have any effect.
Thanks!
