Type 'string' is not assignable to type '{ name: never; weight: number; }'.

I get this error every time I test my app. Could you identify this error and solution?

Argument of type '{ shouldSort: boolean; threshold: number; location: number; distance: number; 
maxPatternLength: n...' is not assignable to parameter of type 'FuseOptions<{}>'. Types of property 
'keys' are incompatible. Type 'string[]' is not assignable to type 'never[] | { name: never; weight: 
number; }[]'. Type 'string[]' is not assignable to type '{ name: never; weight: number; }[]'. Type 'string' is 
not assignable to type '{ name: never; weight: number; }'.

The error occur on this line

const fuse = new Fuse(this.searchList, options)

in my line, this search is put in a function, that I will call it whenever I key anything in my input

 filterQuery(val) {
 const options = {
  shouldSort: true,
  threshold: 0.4,
  location: 0,
  distance: 100,
  maxPatternLength: 16,
  minMatchCharLength: 1,
  keys: ["name"]
};

const fuse = new Fuse(this.searchList, options)

const results = this.sortList(fuse.search(val));
const newResult = [];

for (let i = 0; i < results.length; i++) {
  newResult.push(results[i]);
  if (i > 6) break;
}
this.filteredList = newResult;
}

What I did was define a type for the items I’m passing in, and set that as the type of FuseOptions, and I was good.

interface ItemInterface {
  name: string
}

const items: ItemInterface[] = [{ name: "Mithun" }, ...];

const options: FuseOptions<ItemInterface> = {
  keys: ["name"],
};

const fuse = new Fuse(items, options);

@bkonkle as said in the comment right above yours please check the website on how to properly use Fuse.JS with TypeScript.

You need to split off the options to a separate constant and assign it the type of Fuse.FuseOptions<T> where T is a Generic Type that describes the list your searchinf
