can you show your code?

Hey! Wich part of my code you need? It's a Next js 12 project.

something so i can know what exactly could have caused the error

because just this single cryptic error is not enough for me to know what's wrong

Ye didn't know what to add... Bacause in my code I am not gettin any error, im just trying to migrate the project from node 14 to 18 but when I run dev i get @swc/helpers thing.

This is my package.json, maybe can help:

    "webpack-fix-style-only-entries": "^0.6.1"
  }
}

I am also using Plasmic App for the web design, idk if that is generating the error, but probably no.

For solving the issue i tried to add:

 "@swc/helpers": "0.5.1"

And also tried to swap to Next js 13 but when i do npm install I get:

npm ERR! code ERESOLVE

your error seems to be a bug in whatever package but the bug seems to only be fixed in next 13 https://stackoverflow.com/q/76083438

ye i saw that post... i guess i need to try to go for next 13

aside from this post i cannot know why this happens so can't help, sorry
