Error code DSC-0008

[ttqay]

Hi guys

I had an app that's been working since last year without issue.

Now, since yesterday (Monday 27th), I am hitting problems. Specifically, using the solution provided online (c#) the issue is that
using (WebResponse response = GetWebResponse(request))
using (Stream stream = response.GetResponseStream())
using (StreamReader reader = new StreamReader(stream, Encoding.UTF8))
{
var jsonResponse = JsonConvert.Import<T>(reader);


jsonResponse evaluates to null. When I type the url: https://api.betfair.com/exchange/bet...arketCatalogue into the browser, I get the response:
{"jsonrpc":"2.0","error":{"code":-32700,"message":"DSC-0008"}}


Has something changed with BF API over the weekend?

Thanks

Have you made the necessary changes for the removal of "Expect:100 continue" as per https://forum.bdp.betfair.com/showthread.php?t=2900

Any idea how to code this in excel vba?
Somethimes I got this error. I got no idea how to fix this, and the sampels are not updated yet. :/

I don't think Excel VBA sets the "Expect:100 Continue" flag so I'm not sure any changes are necessary.

Thank you for the answer. It was my mistake. Some other old programs made me this error. So I have just turned them off.
