How to catch the rate limit exception?

[smlbiobot]

I am using your limiter, which is great!

However, I can’t seem to redirect user to a custom page using the exception catching mechanism in sanic. For example:

import sanic_limiter
from sanic import Blueprint

bp_error = Blueprint('Errors and Exception Handling')

@bp_error.exception(sanic_limiter.errors.RateLimitExceeded)
def handle_over_rate_limit(request, exception):
    logger.exception(request.headers.get('x-forwarded-for'), exception)
    return request.app.jinja.render(
        "errors/rate_limit.html",
        request,
        status=429
    )

If I raise the exception directly on an endpoint, I can see that this custom page is shown. However, if a user hits the limit, it just outputs the exception in plain text. What can I do to achieve what I wanted?

can you post more code? have this blueprint registered?

[smlbiobot]

Sorry for the late reply. Yes, this blueprint is registered.

will this suffice? I don’t know how much code you need to see because most of it has nothing to do with the ratelimiter

# app.py

from sanic import Sanic
from sanic_jinja2 import SanicJinja2
from sanic_limiter import Limiter
from cr import blueprints

def get_remote_address(request):
    ip_title = request.headers.get('X-Forwarded-For')
    return ip_title or '127.0.0.1'

app = Sanic(__name__)

app.jinja = SanicJinja2(
    app,
    line_statement_prefix='%',
    extensions=[
        'jinja2_time.TimeExtension',
        'jinja2.ext.do',
        'jinja2.ext.i18n'
    ])

bps = [
    blueprints.bp_admin,
    blueprints.bp_blog,
    blueprints.bp_error,
    # truncated
]
for bp in bps:
    app.blueprint(bp)


limiter = Limiter(app, global_limits=['1/second', '20/minute', '1000/hour', '5000/day'], key_func=get_remote_address)
