Exceeding Max REST POST Request Limit Issue

I'm performing a POST via REST in ServiceNow due to data size limits, which as I understand it, I should be able to increase.  I've already doubled the default values for the two System Properties as specified in ControllingMaxRequestSize but continue to receive errors such as

{"error":{"message":"Exception while reading request","detail":"Rejected large REST payload with content-length = 12126813 bytes. Max allowed: 10485760 bytes."},"status":"failure"}

The "Max allowed" value does not look to have increased based on those System Properties.  So if that's not the solution, how can I POST a large payload to ServiceNow?

--------

FWIW this is my REST code:

var target_table = <target_table_name>;
var requestBody  = <huge_json_string>;


var request = new sn_ws.RESTMessageV2();
request.setEndpoint(gs.getProperty('glide.servlet.uri') + 'api/now/table/' + target_table);
request.setHttpMethod('POST');
request.setAuthenticationProfile('basic', <sys_id>);
request.setRequestHeader("Accept","application/json");
request.setRequestHeader('Content-Type','application/json');
request.setRequestBody(requestBody);
var response = request.execute();
gs.log(response.getBody());

try to split your JSON string into smaller chunks.

Have you tried both of the following?

 

Option 1 (uses JavaScript):

 

var json = new JSON();

 

var jsObj = json.decode(stringValue);

 

 

Option 2 (uses Java):

 

var json = new JSONParser();

 

var jsObj = json.parse(stringValue);
