[Koha] Batch import of MARC fails

[Elaine Bradtke]

We're running 20.05.05
A batch of staged MARC records failed to import, getting stuck at  %90. I
checked the records and validated the MARC in MarcEdit and tried again.
They stage and they look fine, but the import still gets stuck at 90%.
 These are 883 records that were downloaded from our catalogue, edited and
then staged for import. Just last week an export / import of twice that
size worked just fine.
The main difference is these are being imported with a different framework.

>From the log:
Error message (one of many identical)[Mon Dec 07 20:06:48.546903 2020]
[cgi:error] [pid 8587] [client 97.113.80.105:60555] AH01215: [Mon Dec 7
20:06:48 2020] stage-marc-import.pl: Invalid normalization routine required
(biblionumber) at /usr/share/koha/lib/C4/Matcher.pm line 856.:
/usr/share/koha/intranet/cgi-bin/tools/stage-marc-import.pl, referer:
https://catalogue-admin.efdss.org/cgi-bin/koha/tools/stage-marc-import.pl

Also, when it eventually times out, in the staff interface I get: 'Can't
call method "results" on an undefined value at
/usr/share/koha/intranet/cgi-bin/tools/manage-marc-import.pl line 363.'

I'm going to try splitting the file to see if there's a bad record
somewhere, but it seems to me with the many many identical error messages,
that it's not a bad record.
