Amazon EventBridge Rules error with Lambda

Question

Hi Everybody,
I have 2 environments: STG and PROD. I using Medialive for Livestream.
I've created below:

```
Environment STG:
Amazon EventBridge => Lambda function handler event Medialive
```

```
Environment PROD:
Amazon EventBridge => Lambda function handler event Medialive
```

Amazon EventBridge STG and Amazon EventBridge PROD have the same rules like:
```
{
  "source": ["aws.medialive"],
  "detail-type": ["MediaLive Channel State Change"]
}
```

When I config above. I found that events Amazon EventBridge environment STG in Lambda PROD, or opposite events Amazon EventBridge environment PROD in Lambda STG. This leads to conflict when operating my website.

Please explain or help me fix my issues. Thank you so much.

Answer

Recommended option is to create different accounts for the different environments. If you use a single account, each environment should have its own Event Bus in EventBridge. PROD functions will create the rule on the PROD bus and STG functions will create the rule on the STG bus. The functions that send events to the event bus will use an environment variable with the ARN of the bus.

Answer

I am assuming you are using the same Account ID for both environments. This may explain your experience.

If that is the case, you would have to further filter the rule by the ARN of the channel. Essentially you would have something like so:

```
{
"source": ["aws.medialive"],
  "detail-type": ["MediaLive Channel State Change"]
  "detail": {
    "channel_arn": [""]
  }
}
```

and

```
{
"source": ["aws.medialive"],
  "detail-type": ["MediaLive Channel State Change"]
  "detail": {
    "channel_arn": [""]
  }
}
```

You can find the schema for this event here -> https://us-east-2.console.aws.amazon.com/events/home?region=us-east-2#/registries/aws.events/schemas/aws.medialive%40MediaLiveChannelStateChange/version/1
