AWS Route 53 with Boto: alias target name does not lie within the target zone

Question

I am trying to update existing alias_dns_name to different new elb using python boto '2.38.0'

def a_record_alias_update(myRegion, myDomain, elbName, elbZone):
dnsConn = route53.connect_to_region(myRegion)
myZone = dnsConn.get_zone(myDomain+'.')
changes = route53.record.ResourceRecordSets(dnsConn,myZone.id)
add_change_args_upsert = {
    'action': 'UPSERT',
    'name': 'dev.'+myDomain+'.',
    'type': 'A',
    'alias_hosted_zone_id': elbZone,
    'alias_dns_name': elbName,
    'alias_evaluate_target_health': True
}
change = changes.add_change(**add_change_args_upsert)
result = changes.commit()
return result

Error:

result = changes.commit()
File "/Library/Python/2.7/site-packages/boto/route53/record.py", line 168, in commit
return self.connection.change_rrsets(self.hosted_zone_id, self.to_xml())
File "/Library/Python/2.7/site-packages/boto/route53/connection.py", line 475, in change_rrsets
body)

Any help is appreciated !

For anyone coming into this error, the correct way to get the Hosted Zone ID varies for different target types. To find the correct hosted Zone ID, go to the official documentation, scroll down to HostedZoneId and look for your target type.

In this particular case, if you're using an ALB or NLB, you need the CanonicalHostedZoneID attribute of said LB. If it's a Classic LB, you need the CanonicalHostedZoneNameID attribute.
