Description

Link to the code that reproduces this issue

https://github.com/ysulyma/eslint-config-next-repro

To Reproduce
  1. Clone the repository
  2. Run the following
npm install

# works
eslint --config default.json index.tsx

# doesn't work
eslint --config next.json index.tsx
# The prop value with an expression type of TSSatisfiesExpression could not be resolved. Please file an issue ( https://github.com/jsx-eslint/jsx-ast-utils/issues/new ) to get this fixed immediately.

The error only happens when using next/core-web-vitals, not when using the default TypeScript lint settings.

Current vs. Expected behavior

I expected index.tsx to lint without issue, but with the Next plugin I'm receiving the error

The prop value with an expression type of TSSatisfiesExpression could not be resolved. Please file an issue ( https://github.com/jsx-eslint/jsx-ast-utils/issues/new ) to get this fixed immediately.

Research direction

Start with the linked reproduction repository and inspect index.tsx plus the default.json and next.json ESLint configurations. Run the two provided eslint commands to isolate the next/core-web-vitals behavior, then trace the eslint-config-next rule that processes the JSX attribute. Done means the Next configuration lints the satisfies expression without producing the TSSatisfiesExpression error.
