You can also leave -u and use -z "${VAR:-}"
. ${VAR:-}
will be empty if VAR
is unset or empty, but won't trigger the unset variable check.

From man bash
-
-u
Treat unset variables and parameters other than the special parameters "@" and "*" as an error when
performing parameter expansion. If expansion is attempted on an unset variable or parameter, the
shell prints an error message, and, if not interactive, exits with a non-zero status.
So try removing u
from the set
line?
