[QUESTION] What is listening on port 9090

[educob]

Hi.

I tried to connect the libp2p node in the browser to my nodejs libp2p node running on my backend but I got an error:
TypeError: Cannot destructure property 'upgrader' of 'undefined' as it is undefined.

What is running in port 9090 in the example?

How can I connect the libp2p on the browser to a libp2p node in nodejs?

Thanks.
