>I cannot find the root cause of this issue, but multiple libraries that I am aware of have problems searching on particular search terms ( and never the same terms at the same library ). The error they get when they trigger this problem is:
>
>Tag "" is not a valid tag. at /home/koha/kohaclone/C4/Biblio.pm line 1849
>
>Something somewhere is adding empty keys to C4::Context->marcfromkohafield, I think it may have something to do with the analytics feature that was added.
>
>In the while loop for TransformKohaToMarc, there is a line
>
>next unless my $dtm = $db_to_marc->{''}->{$name};
>
>I don't think it's working.
>If I dump $dtm, for each search, I see the dump twice.
>It looks like this:
>$VAR1 = [
>           '952',
>           'w'
>         ];
> $VAR1 = [];
>I think the second time, when it is empty is what's breaking this.
>The next never fails because even though it is empty, it is still a valid arrayref.
>
>The solution I have some up with is to skip over the elements where the arrayref is empty.
