Hey,

Do you have some context for this error, too? Perhaps a small reproducible example and the Node.js version you used?

Had similar issue with any new Websocket() connection used. spotted via jest-offline.
as a solution -> mock websocket

Hey! Perhaps you have a small reproducible example that just depends on Mitm.js? Is the Websocket you refer to the new native Node.js implementation?
