getting WD_UNKNOWN_ERROR when attempting this with a Firestore collection

Sample code below

export function get_testGet(request) {
let options = {
	"headers": {
		"Content-Type": "application/json"
	}
};
return wixData.query("GCM/CollectionName")
.ne("title","something")//ne doesnt work
.find()
.then( (results) => {
    return ok(options);
 } ).catch((err) => {
    options.body = err;
    return serverError(options);
}); 
}
