CORS Error

Hi Bruce,

Please share a screenshot or the details of the command and it’s output, this will help us to understand what your command looks like, see if anything can/should change there.

string url = "http://lvdap38:10086/native/v1/regions/10.10.2.187/49100/QCRS/jescontrol";
HttpClient client = new HttpClient();
client.DefaultRequestHeaders.Add("Access-Control-Allow-Origin", "*");
client.DefaultRequestHeaders.Add("Referer", @"http://lvdap38:10086/native/v1/regions/10.10.2.187/49100/QCRS/jescontrol");
var requestData = new JobSubmission()
{
    ctlSubmit = "Submit",
    subJes = 1,
    JCLIn = "JCL string",
    JCLInBase64 = false,
    dctFName = "G,X",
    batType = 1,
    dctFSN = "",
    dctPath = "",
    xatSwitch = "",
    statusCodes = true
}
string json = Newtonsoft.Json.JsonConvert.SerializeObject(requestData);
var content = new StringContent(json, Encoding.UTF8, "application/json");
var response = await client.PostAsync(url, content);
string responseContent = await response.Content.ReadAsStringAsync();
if (response.StatusCode == HttpStatusCode.OK)
{
    //code to continue processing
}
else if (response.StatusCode == HttpStatusCode.BadRequest)
{
    //code to handle bad request
}
else
{
    //code to handle other status codes
}

JobSubmission is a class with properties corresponding with JSON requirements of the API we’re trying to use.

Error when NOT including Referer header: Code 400, Message “No Origin or Referer header present”

Error when including Referer header: Code 400, Message “No X-Requested-With header present”

Are you using this via a VB / Powershell type script?
Can you consider this approach:
Test this via the ESCWA Docs API page first, URL: 
http://localhost:10086/docs/
>
http://localhost:10086/docs/#/JES/get_v2_native_regions__host___port___region__jescontrol
Once you have that working in there then take the working command to your script.

Hi Kim,

I wanted to provide some additional context regarding the issue with the API call to the QCRS/jescontrol endpoint. We're confident that the endpoint is correct because we are receiving a 400 status code, which indicates a bad request, rather than a 404 status code that would suggest the endpoint itself is not found.

The error message we are receiving points to a potential issue with a missing header in the HTTP request or a CORS configuration problem on the Rocket Enterprise Server. Specifically, it seems to indicate that the server is expecting certain headers to be present in the request, and without them, it cannot process our request properly.

In response to your inquiry about our scripting language, we are not using VB or PowerShell. Instead, we are utilizing C# with the HttpClient class to send the request to the API. This allows us to construct the request and handle the response programmatically.

If you have any insights on the specific headers that may need to be included in the request or if there are adjustments required for the CORS settings on the server, that would be incredibly helpful.

Thank you for your assistance!

Hi Bruce,

I believe this knowledge base article can help:
Title: How to use ESCWA API using curl
URL: https://my.rocketsoftware.com/RocketCommunity/s/article/How-to-use-ESCWA-API-using-curlPlease 
I recommend you to review that, compare what might be different or missing with your C# test and let us know of the result.

That is great news, thanks for the feedback Bruce.

The MDLAP issue we were having was resolved by fixing our incorrect host and port in the endpoint. We were trying to use the host and port of the listener inside the region or server which was not working.

It seems the host and port in the endpoint must be the host and port of the region or server.
