How to modify the postData in a Request

[spikeruk]

Hi,
I am try to change the text in the request body

 pageClient.SubscribeAsync<Fetch.RequestPaused>(async req =>
 {
         if (req.Request.HasPostData == true)
         {
             String postData = req.Request.PostData;
             String modifiedPostData = postData.Replace("ping", "pong");
             byte[] plainTextBytes = System.Text.Encoding.UTF8.GetBytes(modifiedPostData);
             string base64EncodedText = System.Convert.ToBase64String(plainTextBytes);

             await pageClient.SendCommandAsync(Fetch.ContinueRequest(req.RequestId, req.Request.Url, req.Request.Method, base64EncodedText, req.ResponseHeaders));
         }
     }
     await pageClient.SendCommandAsync(Fetch.ContinueRequest(req.RequestId));
 });

Why would this not work?

Seems to work if I use:

 await pageClient.SendCommandAsync(Fetch.ContinueRequest(req.RequestId, null, null, base64EncodedText));

rather than

await pageClient.SendCommandAsync(Fetch.ContinueRequest(req.RequestId, req.Request.Url, req.Request.Method, base64EncodedText, req.ResponseHeaders));

What do you mean by "not work"?

I can only assume the problem might be in the versions incompatibility. The latest ChromeProtocol.Domains package supports Chrome revision that equals or greater than 1367902, with the nearest stable release resolves to 131.0.6778.33 Chrome version.

Older versions of Chrome might have protocol differences.
