Route53 ChangeResourceRecordSets Error #453
Description
When calling Route53's changeResourceRecordSets, I'm getting the following error:
SignatureDoesNotMatch Sender: The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.
The stack trace leading up to this is as follows:
#0 RestXmlProtocol.sendRaw (package:aws_client/src/shared/src/protocol/rest_xml.dart:96)
<asynchronous suspension>
#1 RestXmlProtocol.send (package:aws_client/src/shared/src/protocol/rest_xml.dart:118)
<asynchronous suspension>
#2 Route53.changeResourceRecordSets (package:aws_client/src/generated/route_53/v2013_04_01.dart:397)
<asynchronous suspension>
...
This Route53 client has already been used several times in the same program to enumerate hosted zones and calculate which changes need to be made, so I'm certain that the Route53 client has the proper credentials. It's only the call to changeResourceRecordSets that is failing.
