Read Firehose output in S3 bucket, Validate the Incoming JSON files and move to sucess and error bucket in case of pass and failure

Question

I am getting out from Kinesis Firehose in S3 bucket. I need to read the incoming json files and check if it is valid or not and then move it accordingly to sucess or error bucket in aws. The problem with Kinesis data is that is put each record in one line and there is no comma separator between two records. i have written a code but i need help in fine tuning it as i am not able to parse all the records and how to route the error records. i am putthign the kinesis output data and the Lambda i have written. any help will be highly appreciated. Kinesis Json Data:
