How display nginx error page with flask ?

[BobSquarePants]

Hi everyone,

I've just installed and setup nginx in front of my Flask/Gunicorn

While test it I see that some error page are handled by nginx (that make sense)

I've see that we can define custom page in the nginx config.
But all the example that I've seen are static.

is there a way the set one page/route in flask that will grab the error code ?
Then when can use within the page with jinja for example.

Thanks.

Yes, you can.

...
@app.errorhandler(404)
def handle_404_error(error):
    print(error)

I have already something similar but that catch any ! error --

@app.errorhandler(HTTPException) 
def handle_exception(e):
	return "your error" + e

and even with this one, the Nginx appear anyway.
