I am trying to create a consume stream in kinesis. I created my stream using
`awslocal kinesis create-stream --stream-name mylogstream --shard-count 2` 

which worked. Now I am trying to use lambda consumer, following the tutorial [here](https://docs.aws.amazon.com/lambda/latest/dg/with-kinesis.html#services-kinesis-configure), hence I did

`awslocal kinesis register-stream-consumer --consumer-name con1 --stream-arn arn:aws:kinesis:us-east-1:000000000000:stream/mylogstream`  

which resulted in following error:

>An error occurred (UnknownOperationException) when calling the RegisterStreamConsumer operation:

I tried again with `aws` instead of awslocal:

`aws kinesis register-stream-consumer --consumer-name con1 --stream-arn arn:aws:kinesis:us-east-1:000000000000:stream/mylogstream --endpoint-url=http://localhost:4568` 

which again resulted in same error.

I've configured my aws credentials etc. but nothing seems to fix the issue
