Sock Bind error in Apache Functions Python in local

[jmalbarran]

Actual Behavior

I'm testing Apache Functions and I'm trying to test my function locally

For this, I have started the local server with

fn start --log-level DEBUG --port 8080

and I'm trying to create, deploy and invoke a test function with

fn use context default
fn update context registry mylocalregistry

fn -v init --runtime python fn-local

cd fn-local

fn -v deploy --create-app --app app-local --local
fn invoke app-local fn-local

Result

The invocation (last line) fails with Error invoking function. status: 502 message: Container failed to initialize, please ensure you are using the latest fdk and check the logs

In the server logs I see that the problem is a python socket creation
