Unable to create S3 notification to SNS topic

Question

Hi - I am trying to add SNS topic as event notification to S3 buckets. However, it fails with the following error

```
Unknown Error
An unexpected error occurred.
API response
The ARN failed to satisfy constraint: Member must satisfy regular expression pattern: ^arn:aws[\p{Alpha}\-]*:sns:[\p{Alnum}\-]+:[\p{Digit}]{12}:[\p{Alnum}\-_]{1,256}$
```

Here is my S3 bucket arn:aws:s3:::name and SNS topic arn:aws:sns:us-east-2:accountid:SNSexample.fifo

Accepted Answer

According to the [documentation](https://docs.aws.amazon.com/AmazonS3/latest/userguide/notification-how-to-event-types-and-destinations.html#supported-notification-destinations), FIFO topics are not supported as a S3 event destination:

```
Amazon SNS is a flexible, fully managed push messaging service. You can use this service to push messages to mobile devices or distributed services. With SNS,you can publish a message once, and deliver it one or more times. Currently, Standard SNS is only allowed as an S3 event notification destination, whereas SNS FIFO is not allowed.
