hdiutil fails when trying to create a dmg file at a network location on macOS Catalina. This error does not happen if I try to create the file locally in the temp directory.
cd <network drive>/installers;hdiutil convert -format UDRO -o "target_installer.dmg" "/var/folders/yn/df881_294gzdxbdt5kyttgw400003_/T/installer_DBwJn/target_installer.dmg"

I am also able to modify binaries/dylibs on a network drive without any issues while the hdiutil command is erroring out in the other terminal window. Interestingly the error goes away with a restart, only to reappear after a few successful attempts.
I have tried this command locally and it works. So I am not sure why this fails and then passes on a machine restart. This error didn't happen with mojave.
