alpha server error:io.netty.handler.codec.http2.Http2Exception: Unexpected HTTP/1.x request: GET /** about servicecomb-pack

There is something wrong when Alpha try to call the cancel or confirm method.
Current Omega doesn't catch the exception and it breaks the callback stream connection, then the cancelTransaction won't be invoked.

We are planing to fix this kind of corn case next week.

Sorry, after went through the issue again, I found my laster answer is not related to this issue.
The Client side exception is OK. As the subtransaction is not succeed, Omega doesn't need to call the compensation method of this transaction.
If there is another sub transaction which is called succeed, Omega need to call the compensation method of this transaction.

Yes,the client side didn't has a problem.
How to handle server side error "io.netty.handler.codec.http2.Http2Exception: Unexpected HTTP/1.x request: GET /**" ?

Hi ,
I guess you just try to access the saga event from the restful API.
As you may know, Alpha has two ports to provide service, one is for grpc, the other is restful service.
It looks like you just access the grpc service with HTTP GET request.
