Rollup Plugin - Unexpected Token

Describe the bug

I am trying to build a web-app that I am developing with vite, vue and pinia, during the development, using the script npm run dev or yarn dev I get no error. But when I have to build the web-app, I get a rollup-plugin error, which redirects to a line of code that doesn’t seem to make sense. I’ve also tried deleting the contents of the file, and it builds perfectly, but if I paste the same content into another file, it goes back to not working.

The line of code (reported in the logs below, or 146:20) is this:

143.  // Remove labels from
144.  document.querySelectorAll("#datasetLength label").forEach((el) => {
145.    el.remove();
146.  });
         ^

which is strange, because there is no col 20 on this line.

I can’t upload the whole project to stackblitz (because there are more than 150 files), but I only upload the main files, including the one where I get the error.

There is already an issue with this “subject” only I could not solve it according to my requirement, I also tried to import and implement rollup-plugin-dynamic-import-variables in the configuration in the vite.config.js file (as depicted below), but it seems useless, also because it should be already implemented by default by vite.js

import dynamicImportVars from "@rollup/plugin-dynamic-import-vars";

...
build: {
  outDir: "dist",
  rollupOptions: {
    plugins: [dynamicImportVars()],
  }
},

oh my god… I don’t want to believe it… apparently that was the mistake, I just didn’t notice that I used " instead of `… Thank you very much, it was an attention error then, hahahah. Very kind guys 😉

I don’t see anything strange with AdminsView.vue to tell what’s the issue, other than line 92:

fetch("${import.meta.env.VITE_API_URL}/api/admin/remove?id=" + id, {

not using backticks, but I doubt that’s the issue. I can’t build the repro too to test it out so I’m not sure what else to do. But since you have your local project in hand, you can try slowly removing parts of the code in AdminsView.vue and see what fixes it.
