[Bug]: can't create multiple cloudwatch_event_target with same rule and arn

[livgust]

Terraform Core Version

1.4.2

AWS Provider Version

4.67.0

Affected Resource(s)

• aws_cloudwatch_event_target

Expected Behavior

For a single event with two associated targets, both targets should be created.

Actual Behavior

If the two targets with the same event have the same rule and arn, only one is created. Even if, as in my case, the inputs are different.

I was able to rectify the issue by adding target_id to both targets with different unique values. Only then were both targets created as expected.
