Tekton Triggers with Bitbucket integration

[vyom-soft]

I read your blog, it is verey interesting. I tried with Bitbucket (Code ready container -openshift)

After the event is triggered from bitbucket webhook; The Eventlistener is showing following error message.

{"level":"error","ts":"2021-08-06T15:16:22.931Z","logger":"eventlistener","caller":"sink/validate_payload.go:39","msg":"Invalid event
body format format: unexpected end of JSON input","knative.dev/controller":"eventlistener","stacktrace":"github.com/tektoncd/triggers/
pkg/sink.Sink.IsValidPayload.func1\n\t/opt/app-root/src/go/src/github.com/tektoncd/triggers/pkg/sink/validate_payload.go:39\nnet/http.
HandlerFunc.ServeHTTP\n\t/usr/lib/golang/src/net/http/server.go:2053\nnet/http.(*ServeMux).ServeHTTP\n\t/usr/lib/golang/src/net/http/s
erver.go:2428\nnet/http.(*timeoutHandler).ServeHTTP.func1\n\t/usr/lib/golang/src/net/http/server.go:3279"}

I am not sure why that error msg, is Tekton eventListener (alpha) not able to parse the payload. Could you please provide some pointers.
Thank you.
