AWS Lambda Payload Response

I'm working on an application and our Back-end is written in .NET Web APi Core and Front-end in React. I make an endpoint which gets a JSON list and the size of the list is almost 83 MB. When I, deploy my back-end into AWS Lambda and call my endpoint it gives me an error (Error converting the response object of type Amazon.Lambda.APIGatewayEvents.APIGatewayProxyResponse from the Lambda function to JSON: Unable to expand the length of this stream beyond its capacity.: JsonSerializerException). I already check the Lambda payload response limit is 6 MB, (storing data into S3 from lambda endpoint and then call into Front-End will not work for me), so is there any way I can get that much data through Lambda.

In a single call we cannot retrieve more than 6.2 mb data from AWS lambda or through AWS API.Im also facing the same issue,Either we have to filter data or should do multiple calls

Not with a single call, sorry, you cannot. As described in this link, the payload limit (for synchronous call) is, as you say, 6MB. Asynchronous calls have even lower limits.

I'd suggest you modify your UI/API to narrow your results first, or trap this error and alert the user (or calling service) that the payload is too large (and hence should be aborted, narrowed, or split into multiple calls).
