Upgrading eslint to a new major version (v9) introduces breaking changes. The current versions of @typescript-eslint/parser (^4.31.1 on line 41) and @typescript-eslint/eslint-plugin (^4.33.0 on line 40) are not compatible with ESLint v9. This will cause the lint script to fail.

To resolve this, you must also upgrade these packages to a version compatible with ESLint v9. As of now, this requires using v8.x of the @typescript-eslint packages, which are currently in an alpha state.

You will need to update your dependencies to use these alpha versions, for example:

    "@typescript-eslint/eslint-plugin": "^8.0.0-alpha.35",
    "@typescript-eslint/parser": "^8.0.0-alpha.35",

Please be aware of the potential instability of using alpha releases. You may also need to update your ESLint configuration file due to breaking changes in these packages.

Upgrading ESLint from version 7 to version 9 is a major breaking change that requires updating multiple dependencies and configuration files. The current TypeScript ESLint packages (@typescript-eslint/eslint-plugin@4.33.0 and @typescript-eslint/parser@4.31.1) are incompatible with ESLint 9.x, which requires @typescript-eslint version 8 or later. Additionally, ESLint 9.x uses a new flat config format (eslint.config.js) instead of the old .eslintrc.js format currently used in this project. This upgrade will break the linting process and CI pipeline. To properly upgrade to ESLint 9, you need to also upgrade the TypeScript ESLint packages and migrate the configuration file to the new flat config format.
