Microsoft.Dynamics.Nav.Runtime.NavHttpContent Variable not initialized

[manishratan]

Describe the bug
Have used "Http Client" in one of the extension. And when this extension is triggered, getting error "Microsoft.Dynamics.Nav.Runtime.NavHttpContent Variable not initialized"

To Reproduce
Have created an extension in which i have used "HttpClient" to consume a DotNet webservice. Below are the code:
procedure GetWeb(Parameter1: Code[20];Parameter2:Code[20]);
var
HttpClient: HttpClient;
HttpResponse: HttpResponseMessage;
ResponseText: Text;
URL: Text;
HttpRequest: HttpRequestMessage;
SubFolder: Text[100];
OrderNo: Code[20];
HttpsContent: HttpContent;
HttpsHeader: HttpHeaders;
ReturnValue: ARRAY[20] OF Text[1000];
jObj: JsonObject;
json: Text;
SalesnRec: Record "Sales & Receivables Setup";
begin
SalesnRec.Get();
clear(json);
json := '';
HttpsContent.WriteFrom(json);
HttpsContent.GetHeaders(RequestHeader);
URL := StrSubstNo(SalesnRec."API URL" + Parameter1 + '/' + Parameter2);
HttpClient.DefaultRequestHeaders.Add('WebsiteGuid', SalesnRec."Website-GUID");
IF HttpClient.Post(URL, HttpsContent, HttpResponse) THEN BEGIN
HttpResponse.Content.ReadAs(ResponseText);
Message(ResponseText);
END;
end;

Expected behavior
This error should Not occur. As in previous version(12.XX) of Sandbox environment. Same extension was working properly.

Hi @manishratan, I'm trying to reproduce your issue but I'm unable to do so. I'm using BC sandbox version US Dynamics NAV 13.0 (25251), and AL extension version 2.0.48254.

Can you please provide a ZIP file with a consistent repro and your exact BC and AL version and I'll take another look.

Thanks!

AL Version : 2.045254
BC Version : US Dynamics NAV 13.0 (25432) - Sandbox
US Dynamics NAV 13.0 (25251) - Production

New folder.zip

@manishratan can you start using a later version of your sandbox and then try again and get back to me if it works? Or do you experience this issue in your production environment as well?

[manishratan]

Yes, this issue is in production environment as well.

Hi @manishratan, you are using an un-initialized variable on line 35 in ServceCodeunit.al, this is expected to generate a runtime error. Are you sure you don't mean to use your commented-out statement on line 33 instead?

[manishratan]

@JohanStenberg100 yes, line no 35 was not required. When i removed this line, it worked for me. Thanks :)

Hello Stanleyg33, is the issue still exist. If yes, can you please share the code. And if No, can you please share the solution here.

Hi manishratan,
the issue is because some of the port has been blocked.
once it open, it should be ok.
it's network and security issue.
