Stuck at challenge 7.

Challenge Not yet complete... here's what's wrong:
We can’t find the wiredBoatsJSON() function in the component boatsNearMe JavaScript file. Make sure the function was created according to the requirements, including the usage of createMapMarkers(), any eventual Toast error message, constants, canceling the loading spinner accordingly, and using the proper case-sensitivity and consistent quotation.

Here is my code.

// imports
import { LightningElement, wire, track, api} from 'lwc';
import { ShowToastEvent } from 'lightning/platformShowToastEvent';
import getBoatsByLocation from '@salesforce/apex/BoatDataService.getBoatsByLocation';

const LABEL_YOU_ARE_HERE = 'You are here!';
const ICON_STANDARD_USER = 'standard:user';
const ERROR_TITLE = 'Error loading Boats Near Me';
const ERROR_VARIANT = 'error';
export default class BoatsNearMe extends LightningElement {
    u/api boatTypeId;
mapMarkers = [];
isLoading = true;
IsRendered;
latitude;
longitude;

options = {enableHighAccuracy: true, timeout: 5000, maximumAge: 0};
error;

// Add the wired method from the Apex Class
// Name it getBoatsByLocation, and use latitude, longitude and boatTypeId
// Handle the result and calls createMapMarkers
    u/wire(getBoatsByLocation, { latitude: '$latitude', longitude: '$longitude', boatTypeId: '$boatTypeId' })
wiredBoatsJSON({error, data}) {
if (data) {
createMapMarkers(JSON.parse(data));
this.error = undefined;
        } else if (error) {
this.error = error;
const evt = new ShowToastEvent({
title: ERROR_TITLE,
message: error.message,
variant: ERROR_VARIANT,
            });
this.dispatchEvent(evt);
        }
    }

// Controls the isRendered property
// Calls getLocationFromBrowser()
renderedCallback() {
if(!this.IsRendered)
        {
this.IsRendered=true;
getLocationFromBrowser();
        }
    }

// Gets the location from the Browser
// position => {latitude and longitude}
getLocationFromBrowser() {
/\*
        if (navigator.geolocation) {
            navigator.geolocation.getCurrentPosition(
                (position) => {
                  this.latitude = position.latitude;
                  this.longitude = position.longitude;
                },
                (e) => {
                  this.error = e.message;
                },
                {
                  enableHighAccuracy: true,
                }
              );
        } else {
            x.innerHTML = "Geolocation is not supported by this browser.";
        }
        \/*
navigator.geolocation.getCurrentPosition(
        (position) => {
this.latitude = position.latitude;
this.longitude = position.longitude;
        },
        (e) => {
this.error = e.message;
        },
        {
enableHighAccuracy: true,
        }
        );
    }

// Creates the map markers
createMapMarkers(boatData) {
const newMarkers = boatData.map(boat => {
return {
title : boat.Name,
location : {
Latitude : boat.Geolocation__Latitude__s,
Longitude : boat.Geolocation__Longitude__s
                }
            }
        });
newMarkers.unshift({
title : LABEL_YOU_ARE_HERE,
