SQS event source fails with 'StartingPosition is not valid for SQS event sources'

[mleiseca]

I'd like to use an SQS queue as an event source, but there's a default value being provided for 'StartingPosition'. StartingPosition is not a valid value for SQS events.

Would it work to change this line to only provide a default 'StartingPosition' if EventSourceArn doesn't start with 'arn:aws:sqs'?

Here's the eventSources.json that I'm using (with queue names changed)

{
 "EventSourceMappings": [
 {
 "EventSourceArn": "arn:aws:sqs:us-east-1:sqs-queuename1",
 "BatchSize": 1,
 "Enabled": true
 },
 {
 "EventSourceArn": "arn:aws:sqs:us-east-1:sqs-queuename2",
 "BatchSize": 1,
 "Enabled": true
 }
 ]
}

The error message:

{ InvalidParameterValueException: StartingPosition is not valid for SQS event sources.

Thank you for the report.
SQS event was unsupported.
I'll fix it.

Thanks for the quick response! I've made that change locally and deploying SQS event sources works when it's in place.
