Hi Community,


Can anyone help me on below issue.
When i'm trying to read the data from the D365 standard Rest API response getting the below error "Microsoft.Dynamics.Nav.Runtime.NavHttpContent variable not initialized."
Below is the code i'm using :

var
        client: HttpClient;
        Content: HttpContent;
        gHeaders: HttpHeaders;
        lHeaders: HttpHeaders;
        Request: HttpRequestMessage;
        Response: HttpResponseMessage;
        Url: Text;
        APIKey: Text;
        RString: Text;
        lText: Text;
        ResHeaders: HttpHeaders;
        ResContent: HttpContent;
Begin 
lText := 'scope=APIServices&grant_type=client_credentials';
Content.Clear();

        Content.WriteFrom(lText);
        Request.SetRequestUri(Url);
        gHeaders.Clear();
        lHeaders.Clear();

        Content.GetHeaders(lHeaders);
        lHeaders.Remove('Content-Type');
        lHeaders.Add('Content-Type', 'application/x-www-form-urlencoded');
        Content.GetHeaders(lHeaders);

        Request.GetHeaders(gHeaders);
        gHeaders.add('accept', 'application/Json');
        gHeaders.add('authorization', APIKey);
        Request.Content(Content);
        Request.GetHeaders(gHeaders);
        Request.Method := 'get';
   
        IF client.Send(Request, Response) THEN
            IF NOT Response.IsSuccessStatusCode THEN
                Error('Web service returned error:\\' + 'Status code: %1\' + 'Description: %2',
                        Response.HttpStatusCode(), Response.ReasonPhrase());

        Response.Content().ReadAs(RString);
        JsonReadWrite.ReadJSonToJSonBuffer(RString, JsonBuffer);
END;

Getting the error at this line : Response.Content().ReadAs(RString);

    Yes, I have already Allow HttpClient Request in the extension.

    Do you have Allow HttpClient Requests defined in your extension?
