What are you trying to achieve or the steps to reproduce?

I have a valid, large JSON example that complies with a Joi spec, which I verified as follows:

// array of large json documents
import inputExamples from '../data/input-data.json' assert {type: 'json'}
// joi schema
import inputSpec from '../specs/input.js'
// logs value and no error
console.log(inputSpec.validate(inputExamples[0]))

There is no error importing or validating the JSON example.

What was the result you got?

Sending the exact same validated JSON example to a Hapi endpoint results in a rapidly returned:

{
    "statusCode": 400,
    "error": "Bad Request",
    "message": "Invalid request payload JSON format"
}

I have over-allocated maxBytes for payloads to ~100MB server-wide (the request body is ~1MB). I have enabled debug mode request logging (*). I have added logging to the route handler. I have added failAction handlers with logging to the route's payload and response validation configurations. The large request seems not to reach any of these handlers. Sending a much smaller JSON example to the endpoint works.

What result did you expect?

I expect the large request to reach the same handlers that the small request does, since they are both valid and under size limit.

I did some analysis with Bourne.parse and JSON.parse. The issue is unrelated to request size and is only related to JSON string formatting. Consider the following examples:

try {
  JSON.parse(`{"foo":"bar\""}`)
} catch (e) {
  console.error(e)
}

SyntaxError: Expected ',' or '}' after property value in JSON at position 12

try {
  JSON.parse(String.raw`{"foo":"bar\""}`)
} catch (e) {
  console.error(e)
}

No error

Is there any way to configure Hapi/Bourne to parse the JSON string as a raw string as in the second example? This would fix the issue.

After more analysis the issue originates in the API client (Yaade), not Hapi, so I have opened an issue there.
