Flask url_for() doesn't take a second argument even though it's required

I have the following routes

@app.route("/dashboard/survey/<int:survey_id>/responses",  methods=["GET"])
def responses(survey_id):
    responses = db.session.query(Survey, Responses).join(Responses).filter(Survey.id == survey_id).filter(
        Responses.lan_code == "en").all()

    return render_template('responses.html', responses=responses, kws=kws)


@app.route("/dashboard/survey/<int:survey_id>/responses/delete/<int:r_id>/<participant_folder>", methods=["POST"])
def delete_response(survey_id, r_id, participant_folder):
    #response = Responses.query.get_or_404(r_id)
    #db.session.delete(response)
    #db.session.commit()
    #pfolder = participant_folder.replace("-", "/")
    #print(pfolder)
    #shutil.rmtree('qdas/static/audioResponses/' + pfolder, ignore_errors=True)
    return redirect(url_for('responses', survey_id))

When I try to redirect to 'responses' I get the following error:

TypeError: url_for() takes 1 positional argument but 2 were given

And if remove survey_id from the arguments I get this error:

werkzeug.routing.BuildError: Could not build url for endpoint 'responses'. Did you forget to specify values ['survey_id']?

Is there any way around this?

You need to change this line,

return redirect(url_for('responses', survey_id))

to this one.

return redirect(url_for('responses', survey_id=survey_id))

This is because url_for accepts only one endpoint with an optional number of arguments.
