TS error: property 'responseType' are incompatible?

[pigLoveRabbit520]

const options = {
      method: method,
      searchParams: merged,
      timeout: 6000,
      responseType: 'json',
      resolveBodyOnly: true,
      json: null,
    };
    if (method === 'POST' || method === 'PUT') {
      options.json = data;
    }
    const response = await got(this.baseUrl + uri, options);

vscode ts error:

 Type '{ method: any; searchParams: any; timeout: number; responseType: string; resolveBodyOnly: boolean; json: any; }' is not assignable to type 'Except<Partial<InternalsType>, "hooks" | "retry">'.
        Types of property 'responseType' are incompatible.
          Type 'string' is not assignable to type 'ResponseType'.ts(2769)

The issue is that TypeScript infers responseType: 'json' as type string instead of the literal type 'json'. The fix is to use as const on just that property:

const options = {
	method: method,
	searchParams: merged,
	timeout: 6000,
	responseType: 'json' as const,
	resolveBodyOnly: true,
	json: null
};

This tells TypeScript to treat 'json' as the specific literal type instead of the broader string type, which is what Got's types expect.

Also, you probably don't need json: null if you're not sending a JSON body - you can just omit it entirly.
