Tinypool

Node red crashes on tinypool processworker.initialize when starting using openapi 2.0.
TypeError: Cannot read properties of undefined (reading 'toString') at ProcessWorker.initialize at ThreadPool._addNewWorker at ThreadPool._ensureMinimumWorkers at new ThreadPool at new Tinypool at urlconfig.js

I thought I squashed the error but it did not work. Any ideas? running node-red 4.0, nodejs 18.20.3
