Hi! Sorry for the downtime and inconvenience, this issue was solved this morning and now you can re-queue your build.

do i need to rebuild ? because past build become error

Yes, re-build. If a new build fails without an error message, let me know with the id of the app (seen in url) so we can have a look.
