I get several errors on 

 Use of uninitialized value in subroutine entry at
/usr/share/koha/lib/Koha/Plugins/Base.pm line 182.

177 sub get_metadata {
178     my ( $self, $args ) = @_;
179
180     #FIXME: Why another encoding issue? For metadata containing non latin
characters.
181     my $metadata = $self->{metadata};
182         utf8::decode($metadata->{$_}) for keys %$metadata;
183     return $metadata;
184 }


Verifying that $metadata value is set before applying utf8::decode will avoid
that log error

177 sub get_metadata {
178     my ( $self, $args ) = @_;
179
180     #FIXME: Why another encoding issue? For metadata containing non latin
characters.
181     my $metadata = $self->{metadata};
182     if ($metadata !~ "") {
183         utf8::decode($metadata->{$_}) for keys %$metadata;
184         }
185     return $metadata;
186 }
