vite build error: Rollup failed to resolve import "scheduler"

[JordanMarr]

Today I added @fluentui/react-components v9.25.1 side-by-side with my existing @fluentui v8.
I added the TabList and FluentProvider components to my project and everything looks great.

The problem is that now my pipeline build fails with this:

[vite]: Rollup failed to resolve import "scheduler" from "D:/a/1/s/Product/Source/My.Cool.App/node_modules/@fluentui/react-context-selector/lib/createContext.js".

I don't even know where to begin to resolve this.
Can anyone help?

Here are my dependencies:

 "dependencies": {
    "@fluentui/date-time-utilities": "^8.5.13",
    "@fluentui/react": "^8.110.7",
    "@fluentui/react-components": "^9.25.1",
    "@fluentui/react-focus": "^8.8.30",
    "@fluentui/react-icons": "^2.0.206",
    "@fluentui/theme": "^2.6.34",
    "date-fns": "^2.16.1",
    "prop-types": "^15.8.1",

    "react-dom": "^18.2.0",
    "react-toastify": "7.0.0"
  },

I found the issue. (Apparently I do know where to start.)
My build pipeline was actually calling npm install --legacy-peer-deps (there was a reason I did this a long time ago, but I no longer remember why). The --legacy-peer-deps switch was the cause of error.

I'll leave this here just in case someone else has the same issue.
