I have successfully migrate my Koha 3.2 to Koha 3.8 every thing is OK but when add a new item could not add a error message appear "Can't call method "subfield" on an undefined value at /usr/share/koha/lib/C4/Biblio.pm line 2997" any can hep me please.....?

Often these types of error are due to slightly corrupted bibliographic record and as Koha does more and more with a record, it notices more of them. So what 3.2 could ignore, 3.8 trips over. Look in the koha-error_log file and see if there is more detail on the error. Look at /usr/share/koha/lib/C4/Biblio.pm line 2997 and see what it tries to do in that version of Koha. Test whether it happens with only one bibliograph, or with many. If it's only some, see if there's a pattern or commonality.
