Hello, I keep getting this warning on console while running few scripts which uses URI. Use of uninitialized value in subroutine entry at /usr/lib/site_perl/URI/Escape.pm line 184. Not sure if this is a serious issue w.r.t module functionality. I am using URI version 1.65 Amit

Probably an undefined value is supplied to uri_escape_utf8. I can reproduce it with the latest URI (1.67) and this one-liner: $ perl5.20.2 -MURI::Escape=uri_escape_utf8 -we 'uri_escape_utf8(undef)' Use of uninitialized value in subroutine entry at /opt/perl-5.20.2/lib/site_perl/5.20.2/URI/Escape.pm line 184. So it's probably not an issue with URI::Escape (only that diagnostics could be better here).

That reproduces it, but passing undef to uri_escape_utf8 is probably incorrect? The URLs that are driving this warning would be required in order to address this.
