Problem loading wasm data for SciChart in Django - scichart2d.data = 404

I can only load a blank SciChart surface with a "loading... spinner". Firefox console says:

Uncaught Error: Internal Server Error : http://127.0.0.1:8000/charts/scichart/scichart2d.data

Django is serving scichart2d.wasm correctly, but not scichart2d.data (which is in the same static dir) My HTML and javascript seem to be working, the Webpack bundle loads and logs to console.

I followed the SciChart tutorial here.

I don't know where this problem is coming from. Is it Webpack, Django, or SciChart?

Here's the Django terminal output:


System check identified no issues (0 silenced).

Django version 5.0.2, using settings 'core.settings'

I tried intercepting the request for '/charts/scichart/scichart2d.data' in Django:

charts/urls.py

from .views import scichart, sciChartData,
urlpatterns = [
    path("scichart/", scichart, name="scichart"),     
    path('scichart/scichart2d.data', sciChartData, name="sciChartData")
]

charts/views.py

def sciChartData(request):
    print(request)
    dataURL = static('scichart2d.data')
    return FileResponse(open(dataURL,'rb'),
        filename='scichart2d.data',
        as_attachment=True,
        )

but I couldn't successfully return the .data file to SciChart. The print(request) is

<WSGIRequest: GET '/charts/scichart/scichart2d.data'>

Python Version 3.11.2 pip: Django Version: 5.0.2 node: scichart version": 3.3.567
