Eslint complains about type parameter declaration

[VampishWolf]

I upgraded my wagmi package which brought viem along with it and now when I try to build my project it fails due to eslint errors.

Following is the response from my terminal -

./node_modules/viem/node_modules/abitype/dist/types/human-readable/formatAbi.d.ts:18:35
Type error: Type parameter declaration expected.

  16 |  * @returns Human-readable ABI
  17 |  */
> 18 | export declare function formatAbi<const TAbi extends Abi | readonly unknown[]>(abi: TAbi): FormatAbi<TAbi>;
     |                                   ^
  19 | //# sourceMappingURL=formatAbi.d.ts.map
error Command failed with exit code 1.

What could be done to solve this? Are some changes needed on viem's end or a eslint configuration issue?

@VampishWolf Make sure you are on TypeScript 5.x.

Oh, I was on "typescript": "4.9.4",

What eslint version are you using? Support for const type modifiers was added in 5.5.50.

I'm on these versions
"eslint": "^8.43.0",
