In the inspector section when i want to add a new header for example: Name foo Value bar\r\n Transfer-Encoding: chunked burp gives me : this request is kettled... also after sendig the request burp gives me this error: RST_STREAM received with error code: 0x1 (Protocol error detected) and i should mention that in the inspector the protocol is http2 or https. How can i solve this problem?

Hi Dan, Are you able to provide us with some exact details of the original request and the alterations that you have made to it so that we can take a look at this? Kettled requests are those that are not able to be accurately displayed in HTTP/1 (you can find more information about this here - https://portswigger.net/burp/documentation/desktop/http2).
