zone_journal_compact: could not get zone size: not found

[Kees Bakker]

Running gdb showed that the "not found" comes from this piece of code

isc_result_t
dns_db_getsize(dns_db_t*db, dns_dbversion_t*version, uint64_t*records,
uint64_t*bytes) {
REQUIRE(DNS_DB_VALID(db));
REQUIRE(dns_db_iszone(db));
if(db->methods->getsize!= NULL) {
return((db->methods->getsize)(db, version, records, bytes));
}
return(ISC_R_NOTFOUND);
} That db->methods-getsize is NULL. Here is a piece of the gdb session 
08-Jul-2024 16:39:29.587 dump_done: zone 29.16.172.in-addr.arpa/IN:

{ (gdb) p db->methods->getsize $3 = (isc_result_t (*)(dns_db_t *, 
dns_dbversion_t *, uint64_t *, uint64_t *)) 0x0 The question now is: why 
is that getsize method NULL? Or, should it never have gotten here?
