Hello, I try to set up s3 http notifications but cant seem to figure it out. I tried with python boto3 like this: bucket_notification = s3.BucketNotification('wiaderko0') response = bucket_notification.put( NotificationConfiguration={ 'TopicConfigurations': [ { 'TopicArn': 'Kuba', 'Events': [ 's3:ObjectCreated:*' ] } ] } ) But get the following error: botocore.exceptions.ClientError: An error occurred (InvalidArgument) when calling the PutBucketNotificationConfiguration operation: Unknown I also tried using RGW REST api like with POST like this: http://172.16.97.1:7480/?Action=CreateTopic&Name=test&push-endpoint=http://127.0.0.1:8080 But got error like this: <?xml version="1.0" encoding="UTF-8"?> <Error> <Code>MethodNotAllowed</Code> <RequestId>tx0000000000000000d1e89-005e707912-11e4-default</RequestId> <HostId>11e4-default-default</HostId> </Error> Could any one offer some advice about it. I would appreciate some guide to setting it up as documentation is pretty unclear.
