I use Papaparse lib in typescript.

import Papa from 'papaparse';

Papa.parse(filePath, {
  download: true, 
  header: true,
  dynamicTyping: true,
  skipEmptyLines: true,
};

filepath type is string

I get error on filePath:

No overload matches this call. The last overload generated the following error. The 'string' type argument is not assignable to the 'unique symbol' type parameter.

In @types/papaparse, there is

/**
 * Parse local files
 * @param file a File object obtained from the DOM.
 * @param config a config object which contains a callback.
 * @returns Doesn't return anything. Results are provided asynchronously to a callback function.
 */
// tslint:disable-next-line: no-unnecessary-generics
export function parse<T, TFile extends LocalFile = LocalFile>(file: TFile, config: ParseLocalConfig<T, TFile>): void;

/**
 * Parse remote files
 * @param url the path or URL to the file to download.
 * @param config a config object.
 * @returns Doesn't return anything. Results are provided asynchronously to a callback function.
 */
// tslint:disable-next-line: no-unnecessary-generics
export function parse<T>(url: string, config: ParseRemoteConfig<T>): void;
