bug with several parsers for svelte

[mblandr]

Before You File a Bug Report Please Confirm You Have Done The Following...

• I'm using eslint-plugin-svelte. (*.svelte file linting does not work with the parser alone. You should also use eslint-plugin-svelte with it.)
• I'm sure the problem is a parser problem. (If you are not sure, search for the issue in eslint-plugin-svelte repo and open the issue in eslint-plugin-svelte repo if there is no solution.
• I have tried restarting my IDE and the issue persists.
• I have updated to the latest version of the packages.

What version of ESLint are you using?

8.45.0

What version of eslint-plugin-svelte and svelte-eslint-parser are you using?

• svelte-eslint-parser@0.32.1
• eslint-plugin-svelte@2.32.2

What did you do?

I try mix of TypeScript and JavaScript in the project, so I configured .eslintrc as described in [https://sveltejs.github.io/eslint-plugin-svelte/user-guide/](url)

"overrides": [
{
"files": ["*.svelte"],
"parser": "svelte-eslint-parser",
"parserOptions": {
"parser": {
"ts": "@typescript-eslint/parser",
"js": "espree"
}
}
}
],

but I got there:

[Error - 12:38:00 PM] Error: Error while loading rule '@typescript-eslint/await-thenable': You have used a rule which requires parserServices to be generated. You must therefore provide a value for the "parserOptions.project" property for @typescript-eslint/parser.

Whene I change to this:

"overrides": [
{
"files": ["*.svelte"],
"parser": "svelte-eslint-parser",
"parserOptions": {
"parser": "@typescript-eslint/parser"
}
}
],

error is gone.

What should I change to my settings work?

What did you expect to happen?

working EsLint settings

What actually happened?

[Error - 12:38:00 PM] Error: Error while loading rule '@typescript-eslint/await-thenable': You have used a rule which requires parserServices to be generated. You must therefore provide a value for the "parserOptions.project" property for @typescript-eslint/parser.

It seems that you need to add the following config to all parserOptions.

"extraFileExtensions": [".svelte"],
"project": ["tsconfig.json"],
