I ran into the same thing with Kinesis. The Kinesis API has strict limits on batch size, message size, and rate limiting. Any client writing to Kinesis must deal with all of these constraints and handle errors properly.

I briefly looked at localstack to see how they implemented the Kenesis api and other than a `KINESIS_ERROR_PROBABILITY` option to simulate rate limiting, they did not implement any of the constraints.

Thanks for pointing this, I am adding a few extra validations in v 18 (to be released in a few hours) feel free to raise an issue, this is an open source project but I do review each PR and I keep the code as clean as I can... And yes we do use AI but we know what we are doing :)
