I set up an API Gateway through Gravitee.io and a Springboot application, and everything seems to work fine as per the rest endpoints, running in https also.

Now, I would like to open a websocket connection through the same port (8080), but when the client tries to do it, this error come up server-side:

Handshake failed due to invalid Upgrade header: null

Looking for some solutions online, seems like a port issue, which could be potentially easy to manage with a tomcat server. But there is a way to address this issue using Gravitee.io ?

Thanks

I would advice you to create an issue in gravitee.io repository at https://github.com/gravitee-io/issues/issues/new

Websocket is not yet ready within Gravitee.io
