Server error handling

Hello,

I have been using BasicAuth to manage the logins in my app, but when the user goes to any other page than the main, they get a 403 error. Has anyone successfully implemented serer.errorhandler with Dash?

Here’s what I tried:

server = Flask(__name__)
bootstrap = Bootstrap(server)

app = dash.Dash(__name__,
                server=server,
                )

def no_access(e):
    return render_template('403.html'), 403

server.register_error_handler(403, no_access)

But that didn’t work and neither did:

from werkzeug.exceptions import HTTPException


@app.errorhandler(HTTPException)
def page_not_found(e):
    return render_template('403.html')

I’d really appreciate pointers if anyone has ideas.

Thanks,

Daniel
