UnprocessableEntityException: outputGroups[0].outputGroupSettings.streamName additional property "streamName" exists in object when not allowed; outputGroups[0].outputGroupSettings Object does not mat

Question

I am trying to create an rtmp push input and create a channel with this input only to livestream using aws elemental medialive apis.

I am facing this error, while creating the channel through createChannel API, while i was able to make the input with createInput API.

Error: UnprocessableEntityException: outputGroups[0].outputGroupSettings.streamName additional property "streamName" exists in object when not allowed; outputGroups[0].outputGroupSettings Object does not match "hlsGroup"

This is my channel config:

```

Please help regarding the error.

Answer

Hi,
Your immediate issue is you are using an HLS output group type to send to an RTMP destination. You need to create an RTMP output group instead. Please see https://docs.aws.amazon.com/medialive/latest/ug/rtmp-create-procedure.html

Steve

Answer

Hi, See https://docs.aws.amazon.com/medialive/latest/apireference/channels.html

You can only select one "outputGroupSettings" option per output group, the one you want is:

```
"rtmpGroupSettings": {
            "authenticationScheme": enum,
            "cacheLength": integer,
            "restartDelay": integer,
            "cacheFullBehavior": enum,
            "captionData": enum,
            "inputLossAction": enum,
            "adMarkers": [
              enum
            ]
          },
```
