TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received an instance of Object

Hello!

I'm trying to get a list of folders in a specific folder, using the googleapis library, it gives an error. (typescript)

const folderId:string = "1U4Zucpia-a3S2fwgBJC1omsR4-15KMm2";
const search_query: string = `${folderId} in parents and mimeType contains 'application/vnd.google-apps.folder' and trashed = false`;
const listParams: drive_v3.Params$Resource$Files$List = { q:search_query };
const res: GaxiosResponse = await gd.files.list(listParams);
const listResults: drive_v3.Schema$FileList = res.data;

TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received an instance of Object
