OpenFunction: Apisix & Gateway API is not working.

Description I am trying to configure openfunction working with apisix and gateway api. I was able to create a simple route with the echo server to check if apisix & gateway api is working.

Now i am stuck with OpenFunction.

Environmental

• Operating System Information: ubuntu
• kubernetes version: lastest (with minikube)
• OpenFunction version: lastest

Expected behavior Request the function

Actual behavior Get this error
