            Bug ID: 30816
           Summary: Use of uninitialized value in numeric ge (>=) at
                    /usr/share/koha/lib/C4/Serials.pm
 Change sponsored?: ---
           Product: Koha
           Version: 20.11
          Hardware: All
                OS: All
            Status: NEW
          Severity: minor
          Priority: P5 - low
         Component: Architecture, internals, and plumbing

The code here is:

        for(my $i = 0; $i < $count; $i++) {
            if($calc{'X'}) {
                # check if we have to increase the new value.
                $newinnerloop1 += 1;
                if ($newinnerloop1 >= $pattern->{every1}) {
                    $newinnerloop1  = 0;
                    $newlastvalue1 += $pattern->{add1};
                }
                # reset counter if needed.
                $newlastvalue1 = $pattern->{setto1} if ($newlastvalue1 >
$pattern->{whenmorethan1});
            }

And above:
$newinnerloop1 = $subscription->{innerloop1} || 0; 

I believe this is caused by subscription_numberpatterns.every1 being NULL. 

The default in the database is NULL, but I haven't tested if this can be set
manually from the GUI yet.
