Getting a NoReverseMatch error Django when creating url link in template

not sure why I'm getting this error , I have checked my views and paths , which i think seem fine, the noreversematch error I get shows the arguments ('wonderful', 'bass', 1)' are correct, but it throws back this error:

NoReverseMatch at /instrument-detail/wonderful/1/ Reverse for 'create_eq' with arguments '('wonderful', 'bass', 1)' not found. 1 pattern(s) tried: ['create\-eq/(?P<track_slug>[-a-zA-Z0-9_]+)/(?P<instrument_slug>[-a-zA-Z0-9_]+)/int:id>/$']

here are my views, urls, models, and the template where i have the link to 'create_eq' :

urls.py

path('create-eq/<slug:track_slug>/<slug:instrument_slug>/int:id>/', views.create_eq, name='create_eq'),
path('instrument-detail/<slug:track_slug>/<int:id>/', views.instrument_detail, name='instrument_detail'),

views.py

@login_required
def create_eq(request, track_slug, instrument_slug, id):
    user = request.user
    track = get_object_or_404(Track, id=id)
    instrument = get_object_or_404(Instrument, id=id)
    if request.method == "POST":
        form = EQCreateForm(request.POST)
        if form.is_valid():
            data = form.save(commit=False)
            data.user = user
            data.save()
            return redirect('profile', slug=track.slug, id=track.id)
    else:
        form = EQCreateForm()
    return render(request, 'feed/create_eq.html', {'form': form })



@login_required
def instrument_detail(request, track_slug, id):
    user = request.user
    track = get_object_or_404(Track, id=id)
    my_inst = Instrument.objects.filter(track_id=track.id)
    instrument_obj = get_object_or_404(Instrument, id=id)
    if my_inst.exists():
        instruments = Instrument.objects.filter(track_id=track.id)
        context = {
            'instruments': instruments,
            'track': track,
            'instrument': instrument_obj,
        }
        return render(request, 'feed/instrument_detail.html', context)
    else:
        print('There are no instruments set in your track')
        return redirect('create_instrument', track_slug=track.slug, id=track.id)

models.py

    slug        = models.SlugField(null=True, unique=True)

instrument_detail.html

{% for items in instruments %} 
    <div class="col">

you have a typo mistake, you forgot the < in your url path.
it's <int:id> not int:id>.

path('create-eq/<slug:track_slug>/<slug:instrument_slug>/<int:id>/', views.create_eq, name='create_eq'),
