Clojurians Log v2

I am trying to port a cljsrn project from lein-figwheel + re-natal to Figwheel Main. Right now I am stock with that the optionsUrl in index.js is <http://localhost:9500>[asset-path] and the files are served at <http://localhost:8081/[output-dir]>. If I hard-code an optionsUrl into the generated index.js I get past to the next level of errors in my config. I can’t figure out why the opionsUrl is generated with port 9500 (or how to make it being served there instead of at port 8081, if that is what should happen).
