Front-End Extension Module error

Hello, I want to create an angular front-end module, and I used this documentation.


When executing the yarn start:all, I get the above bug and a white page on the frontend, with the same errors in the console.
Suitecrm8 itself without the extension runs just fine, and with the extension install it still runs fine, it’s only when I try to launch a run command that I get these errors. I’m using laragon, and obviously I’m not getting the console message mentionned at the end of the front end documentation. Should you require additional detail, I would be happy to oblige.
