Describe your issue

Hello,

I have this error when I try to cross compile chirpstack udp forwarder :

ERROR: invalid tag "cross-custom-chirpstack-udp-forwarder-..:aarch64-unknown-linux-musl-bff51": invalid reference format.

I download code source from release tab on github.
folder name is "chirpstack-udp-forwarder-4.8.1"

I don't understand where this "-.." appear but after I read this issue #1077 I understand
So i solved my issue with renaming folder in "chirpstack-udp-forwarder"

I don't know if you think it's an "issue" or just config/settings issue.

thanks you
