OSMWidget Django form location coodinates are incorrect

I have the following form field

point = gis_forms.PointField(widget=gis_forms.OSMWidget(
                            attrs={'map_width': 800,
                                   'map_srid': 4326,
                                   'map_height': 500,
                                   'default_lat': 49.246292,
                                   'default_lon'-123.116226,
                                   'default_zoom': 7,}))

The form is rendered in django as

<form method="post">
  {% csrf_token %}
  {{ form|crispy }}
  <button type="submit">Submit for Review</button>
</form>

But when the data comes in POST the locations are incorrect.

def register_storage(request):
    if request.method == 'POST':
        form = MyGeoForm(request.POST)
        if form.is_valid():
            data=form.cleaned_data
            print(data.get('point'))
            print(data.get('point').srid)

The SRID is showing up as 3857 and weird default coordinates -13645232.541356523 6283123.725041488

I thought it was my django version, but it is updated to 3.1.3 due to some functionality with GDAL. But no luck.

Very lost here.

You must explictly define the SRID in the form's field. I'm not sure why this is the case (you'd think it would default to 4326 like the rest of Django/GeoDjango), but that's the way it seems to be. Your code should read:

point = gis_forms.PointField(
    srid=4326,
    widget=gis_forms.OSMWidget(
        attrs={
            "map_width": 800,
            "map_srid": 4326,
            "map_height": 500,
            "default_lat": 49.246292,
            "default_lon": -123.116226,
            "default_zoom": 7,
        }
    ),
)
