Current Behavior
When creating an SES configuration set event destination, LocalStack logs indicate it was successful, but LocalStack will not return any details about the resource when invoking the ses describe-configuration-set command on the CLI:
❯ awslocal ses describe-configuration-set --configuration-set-name my-config-set --configuration-set-attribute-names eventDestinations
{
"ConfigurationSet": {
"Name": "my-config-set"
}
}However, if you attempt to create that same event destination again, the CLI reports back an error that the event destination already exists, but still returns nothing via the ses describe-configuration-set:
An error occurred (EventDestinationAlreadyExists) when calling the CreateConfigurationSetEventDestination operation: Duplicate Event destination Name.Expected Behavior
When describing the configuration set and having it include event destinations it should output something like the below:
❯ awslocal ses describe-configuration-set --configuration-set-name my-config-set --configuration-set-attribute-names eventDestinations
{
"ConfigurationSet": {
"Name": "my-config-set"
},
"EventDestinations": [
{
"Name": "bounces",
"Enabled": true,
"MatchingEventTypes": [
"bounce"
],
"SNSDestination": {
"TopicARN": "arn:aws:sns:us-west-2:000000000000:ses-bounces-topic"
}
}
]
