response from GET request is truncated (RAK8211)

I am working on a RAK8211 module with Espruino 2v01.17

I have been able to successfully send data using the http module with a "POST" request.
I am now trying to receive data from a server. To do this I am sending this HTTP request:

GET /api/v1/devices/configuration HTTP/1.1
User-Agent: Espruino 2v01.17
Content-Type: application/json
Host: serverPath.com

This is the data I am expecting, and the data that I am actually receiving:

Expected:

[{"type":"Positioning","accelerometer":true,"trilateration":true,"globalPositioning":true},{"type":"EventCadence","smartMode":true},{"type":"Environmental","humidity":true,"pressure":true,"temperature":true,"eventTriggers":true},{"type":"Actions","reboot":false,"dfwUpdate":false,"findDevice":false}]

Received:

[{"type":"Positioning","accelerometer":true,"trilateration":true,"globalPositioning":true},{"type":"EventCadence","smartMode":true},{"type":"Environmental","humidity":t

As you can see, the response is truncated.

I have tried this using both the http.get function and using the http.request function, both results in the same output.

What is interesting is that the content length is 300, but only 168 characters are printed.
When I do a print(res.available()) it returns 168

The response from the server has the following headers:

HTTP/1.1 200
Server: nginx/1.12.2
Date: Tue, 12 Feb 2019 06:28:31 GMT
Content-Type: application/json;charset=UTF-8
Content-Length: 300
Connection: close
X-Content-Type-Options: nosniff
X-XSS-Protection: 1; mode=block
Cache-Control: no-cache, no-store, max-age=0, must-revalidate
Pragma: no-cache
Expires: 0
X-Frame-Options: DENY

Why would the available bytes be showing only 168 when the Content-Length is 300 bytes?

Some more detailed information of things I've tried below:
